Question

A sports ball has a diameter of 20 cm. Find the volume of the ball and select the correct units. Round your answer to 2 decimal places.

Answer 1

Answer:

$V=4,186.67\ cm^3$

Step-by-step explanation:

we know that

The volume of the ball is equal to the volume of a sphere

The volume of a sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=20/2=10\ cm$ ----> the radius is half the diameter

assume

$\pi=3.14$

substitute the values in the formula

$V=\frac{4}{3}(3.14)(10)^{3}$

$V=4,186.67\ cm^3$
