The standard football for all adult and official FIFA competition, a size 5, is approximately 70 centimeters in circumference (a small range of around a centimeter exists).
The formula to calculate the volume of a sphere is 4/3 * Pi * radius^3
So you have to calculate the radius: Circumference = 2 * radius * Pi
70cm = 2 * radius * Pi
Radius = 11.14cm
So volume = 11.14^3 * Pi * 4/3 = approx 5792 cm3
American Football
If you are talking about the ball used in American-style football, the formula is slightly different, because the ball is not a sphere but a prolate spheroid. A prolate spheroid is formed by rotating an ellipse about its long axis.
Instead of one radius, there are two -- a short one, a, and a long one, b, where a is half the length of the ball's minor axis and b is half the length of its major axis.
The formula for the volume of a prolate spheroid is V = 4/3 * Pi * a^2 * b.
It is worth noting that the formula above for the spheroid can be used to calculate the volume of a sphere because a = b for a sphere.

Volume of a football?
It is in cubic units: 4/3*pi*radius^3
Volume and surface area of a football?
Answer assuming that by 'football' you meant one used for soccer: Volume of a sphere (the football) = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2 -------------------------------- Answer assuming that by 'football' you meant one used for American football: Using the dimensions given on Wikipedia for a standard American football (length of ~11 inches and a central circumference of ~22 inches), one can see that the central radius is approximately 3.5 inches. Further assuming that the shape of an American football in long cross-section is roughly that of a Vesica Piscis, one can integrate using the curve produced to yield either surface area or volume contained. Such integrations are particularly easy and straight forward to perform using a numerical approach such as by using a spreadsheet application, like Microsoft Excel. The approximate volume and surface area of a standard football are 232 cubic inches and 189 square inches, respectively. If one wanted to make a rough empirical check of this volume calculation, a properly inflated standard football could be immersed in water and the the displacement carefully measured. Checking the surface area would involve a bit more work but could be accomplished, again roughly, by deflating the ball and cutting it into triangular pieces that individually lie flat; which could then be measured and their collective surface areas summed up.
What does volume have to do with volume?
Unless you are in a reality where nothing has to do with itself, volume has everything to do with volume as it is itself.
What is the volume if d equals 20 and m equals 100?
volume = mass / volume volume = 100 / 20 volume = 5
What is the volume of neon?
The volume of a gas is the same as the volume of its container.
