Question

Find the circumference of the circle to the nearest tenth. Use 3.14 for pi. The length from the center of the circle is 25m

A. 1963.5m
B. 157 m
C. 78.5m
D. 314

Answer 1

The answer is the option B

`157\ m`

Explanation:

we know that

The circumference of a circle is equal to

`C=2\pi r`

where

r is the radius of the circle

In this problem we have

`r=25\ m` ----->the length from the center of the circle

`\pi=3.14`

Substitute in the formula

`C=2(3.14)(25)=157\ m`

Answer 2

circumference = 2xPIxr

length from center of the circle would be the radius = 25

circumference = 2 * 3.14 * 25 = 157

Answer is B. 157 m
