A tennis ball must be between 6.25 and 6.57 cms in diameter, i.e. 3.125 and 3.285 cms radius. If we take 3.2 as the average, and the formula for the volume of a sphere is 4/3 pi r cubed, then:

4/3 * 3.14159 * 3.2 * 3.2 * 3.2 = 137.258 cc

So to the nearest 10 cc it's 140 cc

So you could squash one inside the head of a golf driver.

Well look, if we're doing the pointless trivia thing ... !!
