Question

Find the radius of a sphere with a volume of 180 cubic feet. Round your answer to the nearest tenth.

Answer 1

3.50ft

Explanation:

Given data

Volume= 180ft^3

The expression for the volume of a sphere is given as

Volume=4/3πr^3

substitute

180=4/3*3.142*r^3

180=12.568/3*r^3

180=4.189*r^3

r^3= 180/4.189

r^3= 42.969

cube root both sides

r= ∛ 42.969

r= 3.50ft

Hence the radius is 3.50ft
