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.
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
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).
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

Formula for calculating the area of sphere is : 4 * pi * r * r
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
