The diameter of a tennis ball is 2.5 inches how many tennis balls will fit in a can 2.5 inches in diameter and a foot long?

Answer 1

Let me start by re-wording this question. How many tennis balls will fit within the length of one foot? In order to solve this problem, you need to know the length of a tennis ball. You are given the information that the ball is 2.5 inches in diameter. Knowing that the ball is spherical and that the diameter of a sphere is the same no matter where you measure, the equation can be set up like this. D x N = L Where D=diameter, N=number of balls and L=the length. by plugging in your values the equation becomes 2.5 x N = 12 Now, the problem becomes a matter of isolating the variable (in this case N). To do this you must divide both sides by 2.5. Having grabbed you calculator and done the division, you know that N=4.8. But wait, don't celebrate yet! It is not logical to cut a tennis ball only for the sake of fitting it into a can. Because you only have one foot of space to work with and can't create more, you must round your answer down, getting a final answer of 4 tennis balls. I hope I managed to explain that clearly. If not, let me know and I will be glad to clarify. -Zilduli
