Question

A soccer ball has an interior

diameter of 22cm. How
many cubic centimeters of air
does a soccer ball contain,
rounded to the nearest
hundredth?

Answer 1

5575 cm³

Explanation:

The volume of a sphere is V = (4/3)πr³. If we substitute r = (d/2 where r is the radius and d the diameter), this formula becomes:

πd³

V = (4/3)π·d³/8, or V = -------------

6

and so, if d = 22 cm, the volume is:

π(22 cm)³

V = ------------------- = 5575 cm³
