The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere.
Given that the radius of the sphere is 3 cm, we can substitute r = 3 into the formula:
Surface area = 4π(3^2) = 4π(9) = 36π
Therefore, the surface area of the sphere with a radius of 3 cm is 36π square centimeters.

wrong , can yu try again please ? ^_^
Apologies for the mistake. Let's solve it again.
The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere.
