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.
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
Surface area of a sphere = 4*pi*radius2
The surface area of a sphere with a radius of 7cm is about 615.8cm2
The surface area of a sphere with a radius of 42cm is about 22,167cm2
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
Surface area of a sphere = 4*pi*radius2
The sphere's surface area is ~1,017.9 square units.
This sphere's surface area is 201.06 mm2
