A Section Of A Circle Has Both Endpoints On The Circle. What Is The Section Of The Circle Called? Arc (2023)

Mathematics Middle School


Answer 1

If it is being connected then it is a chord. If it directly goes thru the middle point in a circle, it is either a radius or diameter based on the length.

Answer 2


It is a chord

Step-by-step explanation:

It has two endpoints touching the edge of the circle

< A and < B are complementary and congruent. What is the measure of each of these angles? 90°



< A = < B = 45°

Step-by-step explanation:

First, you have to both concepts: congruent and complementary.

We say two angles are complementary when together they made a 90° angle.

We say two angles are congruent when both have the same amplitude.

For two angles to be complementarity and congruent both have to be the same and together be 90°

So 90°/2=45°

Both angles are 45°

complementary , sum of both angles = 90

Elizabeth ran 36 meters. Haruki ran 8 fewer meters than Elizabeth. Delilah ran 3 fewer meters than Haruki. How many meters did Delilah run? Explain your thinking


36-8 is 28 which is Haruki's distance and his distance minus 3 is delilahs distance which is 25 meters

25 meters because 8 fewer meters for the girl is 28 and 3 fewer meter from the boy is 25 so basically ur just subtracting 8 from 36 which is 28 ans the. 3 from 28 which is 25

At the supermarket,6 mangoes cost $6.12. what is the cost of 8 mangoes\

(Video) How to find the arc length of a circle using the formula


The cost of one is 1.02 so the cost of 8 will be 8.10

Divide 6.12 by 6. That gives you the price of each. It comes out to 1.02. Time 1.02 by 8. That gives you the answer: 8.16

Select the letter of the best answer choice. Use 3.14 or 22/7 for π what is the radius of a circle with a circumference on 141.3 ft? Round your answer to the nearest foot.
A) 4.5 ft
B) 2.25 ft
C) 45 ft
D) 22.5 ft


C = 2πr
141.3 = 2(3.14)r
141.3 = 6.28r
22.5 = r

Translate the triangle (1,-4) (4,-3) (4,-8) 3 units left and 3 units up. What are the new vertices?


9514 1404 393


(-2, -1), (1, 0), (1, -5)

Step-by-step explanation:

Translation 3 units left subtracts 3 from each x-coordinate.

Translation 3 units up adds 3 to each y-coordinate.

(x, y) ⇒ (x -3, y +3)

(1, -4) ⇒ (1 -3), -4 +3) = (-2, -1)

(4, -3) ⇒ (4 -3, -3 +3) = (1, 0)

(4, -8) ⇒ (4 -3, -8 +3) = (1, -5)

An equilateral triangle has symmetry with respect to a line containing an altitude of the triangle. true or false?


Answer: True

Step-by-step explanation:

An equilateral triangle is a triangle with all its three sides are equal.

When we divide it into two equal halves, there will obtain a line of symmetry.

This line of symmetry is the perpendicular bisector of the side of triangle and thus it is the altitude of the triangle.

(Video) Graphing Circles and Writing Equations of Circles In Standard Form - Conic Sections

Therefore, its true that an equilateral triangle has symmetry with respect to a line containing an altitude of the triangle.

True because all sides are equal

Select the letter of the best answer choice. Use 3.14 or 22/7 for π what is the circumference of a circle with a diameter of 21 ft? round your answer to the nearest foot.
A) 132 ft
B) 66 ft
C) 44 ft
D) 33 ft


Because C= d x pi, plug it in, C = 21ft x 3.14, C = 65.94 ft, which is rounded to 66ft, your answer is B.

3.14 x 21 = 65.94 (which rounds up to 66)

Your answer is B, 66.

In Ms. Perrons class 75% of the students are boys. There are 18 boys in class. What is the total number of students in Ms. Perrons class?


25% = 6

So that means if there is 75% of boys

if you add 6 with 18

18+6= 24

Your answer is 24

Bryan is making a cake.He uses 2/3 of a cup of sugar and 2 cups of flour.How much sugar is used per cup of flour


The amount of sugar needed per cup of flour is 1 / 3 cup.

What is fraction?

Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions is first written in India with one number above the other but without a line. The line used to divide the numerator and the denominator were only added by Arabs.


Bryan uses 2/3 of a cup of sugar and 2 cups of flour,

Calculate the amount of sugar as shown below,

The amount of sugar = Amount of sugar for 2 cups flour / amount of flour

The amount of sugar = 2 / 3 / 2

The amount of sugar = 2 / 6

The amount of sugar = 1 / 3

Thus, the sugar needed is 1 / 3.

Step-by-step explanation:

Which mass is the most reasonable for a kitten? A. 100 mg
B. 1 gram
C. 10 grams
D. 1 kg


The average kitten weighs between 1/2lb and 1lb when born, but after 6-7 weeks it can range from 1lb 1 1/2lbs
A. 100mg = 0.000220462lbs
B. 1 gram = 0.00220462lbs
C. 10grams = 0.0220462lbs
D. 1kg = 2.20462lbs
I would say D is your best bet

D is the most reasonable mass of a kitten

What is the arc in a circle? ›

In mathematics, an arc is defined as a portion of the boundary of a circle or a curve. It can also be referred to as an open curve. The boundary of a circle is the perimeter or the distance around a circle, also known as the circumference.

What is the major arc of a circle? ›

An arc whose measure is greater than 180 degrees is called a major arc. An arc whose measure equals 180 degrees is called a semicircle, since it divides the circle in two.

How do you describe an arc? ›

In general, an arc is any smooth curve joining two points. The length of an arc is known as its arc length. In a graph, a graph arc is an ordered pair of adjacent vertices. In particular, an arc is any portion (other than the entire curve) of the circumference of a circle.

How many arcs are in circle? ›

A diameter of a circle divides it into two equal arcs. Each of the arcs is known as a semi-circle. So, there are two semi-circles in a full circle. The degree measure of each of the semi-circles is 180 degrees.

What are the sections of an arc? ›

The region enclosed by an arc and a chord is called the segment of the circle. The region bounded by the chord and the major arc is called the major segment and the region bounded by the chord and the minor arc is called the minor segment.

What is called radius? ›

Radius of a circle is the distance from the center of the circle to any point on it's circumference. It is usually denoted by 'R' or 'r'. This quantity has importance in almost all circle-related formulas. The area and circumference of a circle are also measured in terms of radius. Circumference of circle = 2π (Radius)

What are the endpoints of the edge of the circle? ›

Diameter – A segment that goes through the center of the circle, with both endpoints on the edge of the circle. Chord - A line segment that goes from one point to another on the circle's circumference. Tangent – a line that intersects a circle at only one point.
