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
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.
The volume inside a sphere (that is, the volume of the ball) is given by the formula:-Volume = 4/3πr3where 'r' is the radius of the sphere and 'π' is the constant piThe diameter of a sphere is two times its radius, thus a sphere 8 meters in diameter has a radius of 4 meters.
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Surface Area of a Sphere = 4 pi r2
Surface area of a sphere = 4*pi*radius2
