Question

What is the volume of a sphere with a radius of 9 inches?

A) 108π cubic inches
B) 242π cubic inches
C) 642π cubic inches
D) 972π cubic inches

(I asked this before and I got the answer v≈3053.63, copied straight from Google. I need an answer that is one of the choices...)

Answer 1

Volume of a sphere: (4/3)πr³
r=radius=9 in

Volume=(4/3)*π*(9 in)³=972π cubic inches≈3053.63 in³

answer: D) 972π cubic inches  (3053.63 in³ is correct)
