Circumference = 27 cm
So radius, r = 27/Pi = 4.297183 cm
Then surface area = 4*Pi*r2 = 232.05 cm2

The surface area of this sphere is 2,123.7 units2676 units2
The surface area of a sphere with a radius of 15 units is 2,827 units2
Surface area of a sphere = 4*pi*radius2 Surface area = 4*pi*112 = 1520.530844 square units.
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Circumference isn't squared OR cubed. However, Surface Area is squared and so is Area. So Circumference is just Circumference :)
