Answer 1

im pretty sure its 15

Answer 2

Arc length = 10 pi.

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 (
`(central\ angle)/(360)`.

= 2 * pi * 20 (
`(90)/(360)`.

Arc length = 40* 0.25 pi

Arc length = 10 pi.

Therefor, Arc length = 10 pi.
