Answer 1

im pretty sure its 15

Answer 2

Answer:

Arc length = 10 pi.

Step-by-step explanation:

Given : Circle W has a radius of 20 in and right central angle.

To find :Find the length of arc in term of pi.

Solution : We have given that Radius of circle = 20 in .

Central angle = 90

Arc length =  2 *pi* r ($\frac{central\ angle}{360}$.

                = 2 * pi * 20 ($\frac{90}{360}$.

Arc length = 40* 0.25 pi

Arc length = 10 pi.

Therefor, Arc length = 10 pi.
