There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
One might find the mathematical equation for the surface area of a sphere in a mathematics textbook. One might also find the equation at online math study groups.
Lets pretend that the Earth is a perfect sphere. Surface area of a sphere = 4(pi)(radius)^2. The radius of earth is 6378.1 km. Plug that into your equation and you'll get your answer.
Volume of a sphere = 4/3*pi*radius3 measured in cubic units Surface area of a sphere = 4*pi*radius2 measured in square units
Surface area of sphere is : A= 4*pie*r^2

The formula for the surface area of a sphere is 4*pi*r2
Surface area of sphere is : A= 4*pie*r^2
The surface area of a sphere with radius 6 is: 452 square units.
To find the surface area of a hemisphere, you can use the formula: SA = 2πr^2, where r is the radius of the hemisphere. This formula takes into account the curved surface area of the hemisphere.
Take the surface area of the sphere as of it was whole, and divide by the amount of the sphere that is missing.
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
