You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
The surface area of a sphere with a diameter of 10 is about 314.16 units2
The surface area of a sphere with a diameter of 7cm is 153.9cm2
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
This sphere's surface area is 201.06 mm2
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
The surface area of a sphere with a diameter of 10 is about 314.16 units2
The surface area of a sphere with a diameter of 7cm is 153.9cm2
Surface area of the sphere = 4*pi*63502 = 506707479.1 square km
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
The surface area of a sphere with a diameter of 8 inches is 201.1 inches2
Surface area of a sphere = 4*pi*(diameter/2)^squared
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
