The formula for the surface area of a cylinder is 2nr(r + h) where r is the radius of the cylinder's base and h is its height.
A certain pole has a cylinder-like shape, where the base's radius is 10 centimeters and the height is 2
meters.
What calculation will give us the estimated surface area of the pole in square centimeters?
