That depends on the football's diameter because pi*diameter = circumference
Field diameter of lens B equals field diameter of lens A times total magnification of lens A divided by total magnification of lens B

The size of a high school football is a Wilson TDS. 11.6 inches long, with a diameter of 6.7 inches.
Magnification is inversely proportional to the diameter of the field of view.
ok
Football is the name given to a number of different team sports. All have fairly different measurements, and because many are elliptic (rather than spherical) they do not have diameters anyway. The only football with a diameter is the association football ball, which has a diameter of 21.6 to 22.3 centimetres.
