A can of tennis balls is a cylinder. The formula for the volume of a cylinder is
V = pr2 h
therefore to find the volume:
V = p(1.5)2 (8)
V=18p
241920 in^3 == typical minivan cargo volume (V) 17.576 in^3 == volume of a cube surrounding a tennis ball (v) 13764 == V/v = number of tennis ball sized cubes to fit into the cargo space of a minivan
The groups have 6, 9 and 12 tennis balls Consider how many parts there are: in ratio of 2 : 3 : 4 there are 2 + 3 + 4 = 9 parts. With 27 tennis balls, each part is worth 27 ÷ 9 = 3 tennis balls. Thus, in the first group there are 2 parts = 2 x 3 = 6 tennis balls, in the second group there are 3 parts = 3 x 3 = 9 tennis balls, and in the third group there are 4 parts = 4 x 3 = 12 tennis balls. To check: 6 + 9 + 12 = 27

It is: (4//3*pi*83) divided by (4/3*pi*13) = 512
If every box contained 11 balls that would account for only 99 balls. The hundredth ball has to be placed in a box already containing 11 balls...
Canister holds 3 tennis balls the diameter of the balls is the same as the diameter of the cylinder 6 cm how much space in the cylinder is not taken? Since 3 tennis balls fit in the cylinder, the height of the cylinder is 3 * the diameter of a tennis ball Volume of Sphere = 4/3 * Π radius^3 Volume of Cylinder = height * Π radius^2 The diameter of a tennis ball is 6 cm The radius is 3 cm. Volume of 3 balls = 3* 4/3 * Π * radius^3 Volume of 3 balls = 3* 4/3 * Π * 3^3 Height of Cylinder = 3 * 6 cm = 18 cm Volume of cylinder = 18 * Π * 3^2 Space in the cylinder is not taken = Volume of cylinder - Volume of 3 balls Do the math, you should get 169.6 cc for the space in the cylinder is not taken.
How many balls are in one can? Three? If so, then calculate the volume of one ball and multiply by three. That's the volume occupied by the balls. The volume of a sphere is given by the formula V = 4(Pi)r3/3. Now calculate the volume of the cylinder. Assume that its height is three times the diameter of a ball (if there are three balls in the can). Remember that the diameter is twice the radius. Also, assume that the radius of the can is equal to the radius of one ball. The volume of a cylinder is given by the formula V = (Pi)r2h. Now subtract the volume of the balls from the volume of the can.
If the can is a right circular cylinder, as appears to be implied by the question, r represents the radius, and h represents the height, the volume is pi X r2h = about 56. cubic inches. (The last digit is depressed to show that it may not be significant, because the height is state with only one significant digit.)
Standard tennis balls have a radius between 32.71 mm and 34.29 mm
I regret to inform you that I am unable to provide you with an answer to your question. However, I can tell you how you would go about finding the answer. The first step would be to find the volume of your can. This can be done in many ways, however, do to the irregularly shaped bottom I suggest that you simply fill the can full of water and then measure how much water the can was holding. Whatever number you get will be the can's volume in units cubed. Your second step is to find the volume of a tennis ball. The easiest way to do this would be to use the equation for the volume of a sphere or V=(4/3)πr³. Knowing that the radius of a tennis ball is 1.125 inches you simply plug that into the equation and get V≈5.964 inches cubed. Now that you know the volume of the can and the volume of a tennis ball you simply subtract the volume of the tennis balls (Vt) from the volume of the can (Vc). The equation would look like this. Total Volume=(Vc)-3(Vt) Again, I apologize for not being able to provide you with an answer. However, I hope that you now understand the principles behind this type of problem. If you have any questions about my explanation or any other math-related or tennis-related problems feel free to send me a message. Zilduli
If the radius of each tennis ball is 3cm, then the diameter of each ball would be 6 centimeters. And since there are 3 balls, the height of the cylinder would be 18 centimeters.
My son and I did this experiment as a science fair project. We put 2 tennis balls in the freezer for 1 hour. We also put 2 tennis balls in heating pad (high setting) for 1 hour. We also used 2 room temperature balls. We dropped the balls from 80" onto a tile floor and measured the height of the bouces with a measuring tape. The results were fairly dramatic. The tennis balls from the freezer bounced an average of 25 inches. The room temperature balls bounced a full 50 inches. The warm balls bounced an average of 55 inches. Obviously there was a significant difference between the bounces of cold and warm tennis balls.
Well, let's first calculate the volume of the can. So, we would use πr2 to find the area of its base, so if 7 is the diameter, 3.5 is the radius, or r. Assuming 3.1415 for π, 3.5 * 3.5 = 12.25. 12.25*3.1415 = 38.483375. Now, we multiply this by the height, so 38.483375*20=769.6675. Then, we will calculate the volume of each tennis ball, each has a radius of 3, being that they have a diameter of 6, as the diameter is twice of the radius. To calculate the area of a tennis ball, we will use the formula 4/3πr3, using again 3.1415 for pi, and 3 for r. 33 equals 27, this multiplied by 3.1415 is 84.8205, then this multiplied by 4/3 is 113.094. Now, we have our volumes, the cylinder or can is 769.6675 cm3 and our balls are each 113.094 cm3, which we will multiply by three because there are three balls in the can, giving us 339.292 cm3, which is the total volume that the tennis balls take up. Now, we simply find what percent of 769.6675 339.292 is. So, we will divide 339.292 by 769.6675 to get approximately 0.440829319, which me multiply by 100 to get a percent, giving us 44.0829319, which is the percent of the can that the tennis balls take up.
Since a tennis ball has a diameter that is greater than 2 inches, the answer is 0.
According to the 2006 regulations, the International Tennis Foundation specifies that all regulation tennis balls should be between 2.575 inches 2.875 inches in diameter, depending on the type of ball.
I assume this is true or false... since it is only a statement and not a question. True
tennis balls are furry and raquet balls are not . tennis balls are also bigger.
