Surface area of a sphere with radius r = 4(pi)r2
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
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.
Finding the radius of a Sphere by using the surface area is a multi-step mathematical equation. The radius (r) of a sphere with a surface area of 1742400ft is 372.365ft.

Surface area of sphere is : A= 4*pie*r^2
The formula for the surface area of a sphere is 4*pi*r2
The surface area of a sphere with radius 6 is: 452 square units.
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
The surface area of a sphere is 4 π r2. Since a hemisphere is half of a sphere, the equation will be 2 π r2.
