Question

What is the radius of the inside of the sewer pipe if the circumference of the outside of the pipe is 150.72 inches?

Answer 1

24in

Explanation:

Given data

Circumference= 150.72in

The expression for the circumference in terms of the radius is

C=2πr

Substitute

150.72=2*3.142*r

150.72=6.284r

150.72/6.284=r

23.98=r

Hence the radius is =24in
