The approximate volume of the table tennis ball in cubic millimeters is 33,493 cubic millimetres
Since the ball is spherical in nature, the formula for calculating the volume of the tennis all is expressed as:
[tex]V = \frac{4}{3}\pi r^3[/tex]
r is the radius of the tennis ball
Given the following:
diameter = 40mm
radius = 40/2 = 20mm
Substitute the radius of the ball into the formula;
[tex]V = \frac{4}{3}\pi (20)^3\\V= \frac{4}{3}\times 8000 \pi \\V = \frac{32,000 \pi}{3}\\V = \frac{100,480}{3}\\V = 33,493.33mm^3[/tex]
Hence the approximate volume of the table tennis ball in cubic millimeters is 33,493 cubic millimeters
