The surface area (SA) of a sphere is given by the formula:

SA = 4πr^2

where r is the radius of the sphere.

In this case, the radius of the football is 8cm. Substituting this value into the formula, we get:

SA = 4π(8cm)^2

Simplifying the expression inside the parentheses, we get:

SA = 4π(64cm^2)

Multiplying out, we get:

SA = 256π cm^2

So, the surface area of the football is 256π square centimeters, or approximately 804.25 square centimeters if we use the approximation π ≈ 3.14159.
