Radius
Area
Circumference
Radius is distance from centre of sphere to the surface of the circle usually represented as r
Diameter is distance from one point on surface to another point in
on the surface with the line passing through the centre of the circle
Diameter (d) = 2 * r
Volume is the volume of the sphere
Volume (v) = 4/ 3 * π * r^{3}
Surface Area is the total surface area of the sphere
Surface Area (a) = 4 * π * r^{2}
