The surface of a sphere is calculated pi*d2 or 4 *pi*r2
So if you have a sphere with diameter 8 (units) the area is 804.25 inches squared
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 in, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 square inches
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
Use this formula (Ï€ = Pi): Surface area = 4Ï€r2
The surface area of a sphere with a radius of 2 is about 50.27 units2
Diameter: 41/pi = 13 inches rounded to a whole number Radius: 13/2 = 6.5 inches Surface area of the sphere: 4*pi*6.5 squared = 530.929 square inches to three decimal places
637.045 square inches (rounded)
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 in, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 square inches
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 radius of 13ft is about 2,123.7ft2
The surface area of a sphere with a radius of 5m is 314.2m2
The surface area of a sphere with radius 6 is: 452 square units.
The surface area of a sphere that has a radius of 10 is: 1,260 square units.
Use this formula (Ï€ = Pi): Surface area = 4Ï€r2
The surface area of a sphere with a radius of 4.75 is about 283.5 units2
The surface area of a sphere with a radius of 2 is about 50.27 units2
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.
