Question

20) Find the volume of a sphere with a diameter of 8.

A) 3/256 pi cubic units
B) 3/156 pi cubic units
C) 256/3 pi cubic units
D) 265/3 pi cubic units

Answer 1

C) 256/3 pi

Explanation:

Volume of a sphere is 4/3 × pi × r^3

The radius is half the diameter = 4

`\frac{4 \pi * {4}^(3) }{3} \\ = (4 (64)\pi)/(3) \\ = (256\pi)/(3)`
