What is the area of a sphere?
The area of a sphere is actually a surface area as a sphere is a 3 dimensional object. The area of a sphere is equal to 4 x pi x the radius squared. It's derivation is very interesting and is done by using multi sided polygons inside the sphere, further individual research is recommended.
Four thirds x pi x radius cubed is the volume of a sphere and 4 x pi x radius squared is the formula for the area of a sphere
