2 balls of the same diameter can have the same mass. Equally, they can have a different mass. (i.e Having the same diameter does not automatically mean that they are the same mass).
However, they will have the same volume. In maths, volume of a sphere (ball) =4/3*(pi)*radius^3. Hence volume is directly proportional to diameter (radius is half the diameter).
Mass is a measure of "how dense something is" (e.g lead, wood and concrete are all dense, whereas meringue and mousse are not) Mass has nothing to do with the size of the ball, only what substance the ball is made up of. Whereas volume is easiest of think of as "how much water can I fit in this" (volume is directly related to the size of the container).
Hope that helps, rather than confuses.

You have density of 3 equal size balls if density of one ball is twice that of the other 2 what conclusion can you draw about its mass?
Density is mass divided by volume. If the density is greater and the volume is the same then the mass must also be greater for the same size 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?
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.
What is the mass of a snooker ball?
2 1/6 inches on a full size table. 2" on a 7 to 9 ft table.
A flywheel's diameter is twice that of another of the same shape and mass The larger diameter flywheel's rotational inertia is?
four times the other's Because Rotational Inertia for a flywheel with its axis through the center is I=mr^2; I=m(2r)^2 I =m4r^2
If you dropped a 6 inch diameter 20 pound ball and a 2 inch diameter 20 pound ball which would hit the ground first?
They will land at the same time, since the acceleration due to gravity is exactly the same for any object of any mass on Earth, at approximately 9.8 m.s-2
Are billiard balls different to snooker balls?
The correct answer is "maybe". The original game of billiards refers to English Billiards and this is nothing like pool. English billiards uses balls that are 52.5mm (2-1/16 inches) in diameter. The Carom Billiards games, such as Three Cushion, is also nothing like pool. Carom billiard games use balls that are 61.5mm (2-7/16 inches) in diameter. Both English and carom billiard ball sets use 3 balls: a white one, a red one, and another white one with a spot on it (sometimes substituted with a yellow ball). However, the term billiards today nearly always refers to the Pocket Billiards games, most likely 9 Ball or 8 Ball. These are also referred to as pool games and all use the same balls. These balls are 57.15mm (2-1/4 inches) in diameter. There are 15 numbered balls and a white cue ball in a typical set.

How many tennis balls can fit in a 2x2x2 box?
Since a tennis ball has a diameter that is greater than 2 inches, the answer is 0.
Why is that C equals 2 pie raduis and C equals pie Diameter mean the same thing?
2 radiuses make the diameter
Calculate the diameter of a cylinder whose height is the same as its diameter and whose volume is 220cm?
Volume = Height * Area of Circle Area of Circle = pi*(Diameter/2)^2 Height = Diameter Volume = Diameter*(pi*(Diameter/2)^2) Volume = (pi/4)*Diameter^3 Diameter = (4/pi) * Volume ^ (1/3) Diameter = (4/3.14)*220^(1/3) ≈ 6.54 cm
