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 7cm is 153.9cm2
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
The surface area of a sphere with a diameter of 10 is about 314.16 units2
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 12-inch diameter sphere is 452.39 square inches.The formula for surface area of a sphere is 4*pi*r2 where r=radius
The surface area of a sphere with a diameter of 7cm is 153.9cm2
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
The surface area of a sphere whose diameter is 18cm is 1018cm2
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
