Tennis balls are sold in cylindrical cans with the balls stacked one on top of the other. A tennis ball has a diameter of 6.7 cm
andrey2020 [161]

Answer:

629.92 cm^3

Step-by-step explanation:

The minimum volume of the can that can hold 4 tennis balls must have at least the same volume as 4 tennis balls.

The volume of one tennis ball, V = \frac{4}{3}\pi  r^3

where r = radius of the tennis ball

The diameter of a ball = 6.7 cm

Its radius will be = 6.7 / 2 = 3.35 cm

Volume, V, will be:

V = \frac{4}{3}\pi  (3.35)^3

V = 157.48cm^3

Hence, the volume of 4 balls will be:

4 * V = 4 * 157.48 = 629.92 cm^3

The minimum volume that the cylindrical can has to have is 629.92 cm^3.
