Volume of a ball or sphere = 4/3*pi*radius3 and measured in cubic units
Assuming that the ball is spherical in shape, the volume of a sphere is given by the formula(4/3)(pi)(radius)3 cubic unitsSource: www.icoachmath.com
Find the volume for the whole sphere (4/3 x pi x radius cubed) then divide by two.
Yes, but only if there is air, dust and other molecular scale debris attached to the ball. In a perfect universe, where nothing but the ball enters the water, then the volume would be exactly the same as that of the sphere.
You can look at this problem by stating it differently. Basically we just need to find the volume of a sphere with a given diameter. If we look up the formula for the volume of a sphere we get: Volume equals four thirds times pi times the radius cubed. The radius of a sphere is equal to 1/2 of the diameter, and pi is equal to about 3.14. Using this information we can find the volume of our rubber ball. V=(4/3)*pi*(1/2d)^3 So if you had a rubber ball with a 2 in. diameter, you would have a volume of about 4.19 in^3. Hope that helps.
