Sphere
A sphere consists of all points in space that
are a fixed distance (the radius) from a given
point (the
center).
The radius of a sphere is the distance from the center to any point on the sphere.
The surface area of a sphere is four times the square of the radius.
The volume of a sphere is four-thirds times the cube of the radius.
ExampleIf a sphere has a radius of , then its surface area isand its volume is
