Modern tennis balls must conform to certain criteria for size, weight, deformation, and bounce criteria to be approved for regulation play. The International Tennis Federation (ITF) defines the official diameter as 6.54–6.86 cm (2.57–2.70 inches). Balls must have masses in the range 56.0–59.4 g (1.98–2.10 ounces). Yellow and white are the only colors approved by the ITF, and most balls produced are a fluorescent yellow known as "optic yellow", first introduced in 1972 following ...
See Answer. Best Answer. Copy. The volume of a sphere is: V = 4πr3/3 and the density is approx. 0,4 g/cm3. Wiki User. ∙ 2015-11-20 18:43:27. This answer is: 👍Helpful.

Since the tennis ball density is less then the density dried beans the tennis ball will tend to rise and float on top of the dried beans. This would be equivalent to wood floating on water. So depending of the time and how vigorous the shaking is the ball will rise and the volume of tennis ball replaced with more dried beans.

Basketball rubber ball- 18g Tennis ball- 58 g Baseball- 148g Then we discussed the differences between each ball's mass versus its volume. The baseball had a lot more mass in the same amount of space than the other two balls. This means that it has a higher density, its molecules are packed much more tightly together.
a. The ball shall have a uniform outer surface consisting of a fabric cover except for the Stage 3 (Red) foam ball. If there are any seams they shall be stitchless. b. The ball shall conform to one of the types specified in the table immediately below or in the table under paragraph (d). TABLE 1. TENNIS BALL SPECIFICATION
Made of high-density foam, these balls won’t have anywhere near the destructive power of fast-moving rubber tennis balls, rendering them safe for regular use indoors. Foam practice tennis balls are the same size and shape as traditional balls, yet lack the weight and rigidity, allowing for safer play.
Keep the intimidation factor low as you introduce beginners to the game of tennis—this ball is made of foam and is 25% larger than a traditional ball. Extra-large size is easier to see, handle, and hit, while still offering a realistic bounce and authentic playability on the court.
