Question

A sphere has a radius of 1.5 inches.

What is the volume of the sphere rounded to the nearest tenth?

Use 3.14 for pi.

9.0 in³

14.1 in³

28.3 in³

36.4 in³

Answer 1

14.1 is the answer

Answer 2

volume of a sphere = (4/3)πr³
π=3.14
r=1.5

v = (4/3)(3.14)(1.5)³
v = (4/3)(3.14)(3.375)
v = 14.13 in³

your answer is the second choice, 14.1 in³
