Question

What is the volume of a sphere with a diameter of 9 in.?

A. 40.5π in3 B. 121.5π in3 C. 324π in3 D. 972π in3

Answer 1

r = d/2 = 9/2 = 4.5
volume of sphere = 4/3*π (r) ^3

= 4/3π(4.5)^3

= 121.5π in^3

Answer 2

Answer: 121.5 in³

Step-by-step explanation:


`\textnormal{Volume }= \cfrac{4}{3} \pi (4.5)^3 = 121.5 \pi \ in^3`
