Question

The diameter of a sphere is 16 in. What is the sphere's volume? Round to the nearest tenth, if necessary. A) 971.7 in3 B) 1072.3 in3 C) 1137.4 in3 D) 2144.7 in3

Answer 1

Volume of sphere = 4/3πr³

r is radius.

Radius = diameter/2 = 16/2 = 8

Volume = 4/3(3.14)(8)³
Volume = 2143.57

Rounded to nearest tenth would be 2144.7 in³

The answer is D.

Hope this helps :)
