Volume of the beach ball: 4/3*pi*radius^3
10 inches
You'll need to know its radius because its volume = 4/3*pi*radius cubed
First we have to find the radius because the diameter is twice the radius: 4/3*pi*radius3 = 28 radius = 1.883749459 (worked out by making the radius the subject of the formula) diameter = 3.767498918 or 3.77 inches to 2 d.p.
Volume formula for a sphere is 4/3*π*r3 so volume of ball with radius of 4.6 cm is 4/3*3.14159*(4.6cm)3 = 407.72 cm3
Volume = 4/3*pi*93 = 3053.628059 or about 3054 cubic cm

You can determine the volume of a steel ball bearing by using the formula for the volume of a sphere, V = (4/3) * π * r^3, where r is the radius of the ball bearing. Measure the diameter of the ball bearing and divide it by 2 to calculate the radius, then plug it into the formula to find the volume.
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.
Assuming the ball is a perfect sphere, it depends on the radius. The volume of a sphere is (4/3)(pi)(r^3).
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.
