Question

What is the radius of a hemisphere with a volume of 5320\text{ in}^3,5320 in 3 , to the nearest tenth of an inch?

Answer 1

13.6 in

Explanation:

volume of a hemisphere = (2/3) x (n) x (r^3)

n = 22/7

r = radius

5320 = 2/3 x r^3 x 22/7

r^3 = 5320 x 3/2 x 7/22

find the cube root of both sides

r = 13.6
