Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
The formula for the surface area of a sphere is: 4 pi r 2
Formula for finding the surface area of a sphere = 4*pi*radius2 in square units. Formula for finding the volume of a sphere = 4/3*pi*radius3 in cubic units. Or did you mean the formula for finding the area of a square? in which case it is Length*Height in square units.
To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
Surface area of a sphere = 4πr2
Archimedes.
If you mean 4*pi*r^2 then it is the formula for finding the surface area of a sphere
Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
The formula for the surface area of a sphere is: 4 pi r 2
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.

The formula for the surface area of a sphere is 4*pi*r2
Surface area of a sphere = 4πr2
Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone
Surface area of a sphere = 4*pi*radius2
4*pi*r2. because surface area is equal to circumference of circle.
