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.
I assume this is true or false... since it is only a statement and not a question. True
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.)
To a first approximation, a tennis ball is a sphere. The volume of a sphere is V = 4/3 π r3, where r is the radius of the sphere. So measure the diameter of the tennis ball, divide by 2 to get the radius, and then apply the formula above. You could also measure the volume of a tennis ball by measuring the volume of water that it displaces.
Surface area: 4*pi*radius2 = 28 Making the radius the subject of the above gives it a value of 1.49270533 or about 1.5 inches
They are spheres. They cannot therefore have different geometrical properties. To alter surface to volume ratios you would need to alter the shape. The study of mathematical shapes is called topology.
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.

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
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.
40 millimeters
It all depends on which side you are measuring, the inside or the outside. The inside is shorter than the out because of the thickness of the balls covering. According to Wikipedia a tennis ball is 2.63 in. in diameter. The diameter on the inside will be a little closer to 2.50 in. The thickness of the balls covering is measured millimeters, and I don't know what that would be.
There is no relationship between the two. You can have tall thin cylinders (like boxes of Pringles or tennis ball boxes) or short and squat (like jam jars).
Standard tennis balls have a radius between 32.71 mm and 34.29 mm
