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.
