Question

A sphere has a volume of 1 cubic foot. What is the approximate diameter of the sphere? A. 1.2 ft B. 1 ft C. 0.6 ft D. 0.3 ft

Answer 1

C. 0.6ft

Explanation:

Given data

Volume of sphere= 1 cubic foot

DIameter= ????

The expression for the volume of a sphere is given as

Volume= 4/3πr^3

Substitute

1= 4/3*3.142*r^3

1= 4.189r^3

r^3= 1/4.189

r^3= 0.2387

Cube root both side

r= ∛0.2387

r= 0.62

r=0.6ft approx
