You replace the radius in the formula, and do the calculations, to obtain either the volume or the area, depending on what formula you are talking about.
The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
Because when working out volumes the answer is given in cubic units and the radius in the formula for finding the volume of a sphere is cubed: Volume of a sphere in cubic units = 4/3*pi*radius3
Using the radius, the formula is: V = 4/3(PI*r3)
The formula for the surface area of a sphere is: 4 pi r 2
Surface area of a sphere = 4πr2

The formula for calculating the surface area of a sphere is 4πr², where r is the radius of the sphere. This formula represents the area covered by the curved surface of the sphere.
Using the radius, the formula is: V = 4/3(PI*r3)
The formula for the surface area of a sphere is: 4 pi r 2
The formula for calculating the charge density of a sphere is Q / V, where is the charge density, Q is the total charge of the sphere, and V is the volume of the sphere.
The formula for calculating the moment of inertia of a solid sphere is (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
The surface charge density formula of a sphere is Q / 4r, where is the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
The charge density formula for a sphere is Q / V, where is the charge density, Q is the total charge, and V is the volume of the sphere.
Surface area of a sphere = 4πr2
The formula for the surface area of a sphere is 4πr2. The formula for the volume of a sphere is 4/3πr3.
Formula for volume of a sphere = 4/3*pi*radius3 measured in cubic units.
