Question

A ping pong ball has a diameter of 40 millimeters. What is the volume of the ping pong ball in cubic millimeters

A. 6000pi
B. 1600/3 pi
C. 2560000/3 pi
D. 32000/3 pi

Answer 1

D. 32000/3 pi

Explanation:

Given

Diameter D of ball = 40 mm

radius =
`(D)/(2)=(40)/(2)=20 mm`

Solution:

Volume of Spherical ball =
`(4)/(3) * pi* r^3= (4)/(3) * pi* 20^3 = (32000)/(3) * pi`
