Question

What is the volume of a ball if the diameter if the ball is 6 inches? Leave your answer in terms of π.

A) V = 12 π cubic inches
B) V = 36 π cubic inches
C) V = 288 π cubic inches
D) V = 27.75 π cubic inches

Answer 1

Upon calculation, I believe the correct response is B.) V= 36 Pi cubic inches.

Answer 2

Volume = 4/3*pi*r^3
As diameter = 6 inches
Radius = Diameter / 2
Radius = 6/ 2
Radius = 3 inches
Putting the value of r in the formula :
=4/3*pi*3^3
=4/3*pi*27
= 36*pi
So according to above explanation,
B) V = 36 π cubic inches , is the correct answer.
