The formula for the surface area of a sphere is 4 (pi) r2
For a radius of 5 in, the surface area is
4 (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 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
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)
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
615.75 inches2615.75 inches2
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 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.
The surface of a sphere is: A=4? r2 From this, the surface are changes as the square of the radius. It does not change linearly.
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
The surface area of a sphere with a radius of 4.75 is about 283.5 units2
