A sphere is perfectly round, composed with set of points that are all the same distance from the centre of the sphere. A ball is an example of a sphere.
The volume of a sphere is 2/3 that of a circumscribed cylinder (Archimedes).
Enclosed Volume of a Sphere
|Volume (V)||=||4||×||π||×||radius cubed|
r is the radius of the cross section of the sphere.
Surface Area of a Sphere
A sphere has only one single curved surface area (face). A sphere has no edges.
|Surface Area (A)||=||4||×||π||×||radius squared|
