Question

The figure shows three tennis balls in a can with each tennis ball

having a diameter of 2 inches. What is the total volume (in cubic inches) of the air
space around the tennis balls? *

Answer 1

Volume of 1 ball = 4/ 3 * pi* *r^3

=4/3 * pi* 1.25^3

=8.18 cu.in

3 balls volume = 8.18 *3

= 24.54 cu.in

empty space = 36.8 - 8.18= 27.68 cu.in
