What is the surface area of a sphere with a radius of 7cm?

The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7cm, we get 4π(7)^2 = 4π(49) = 196π. Therefore, the surface area of a sphere with a radius of 7cm is 196π square centimeters.
