SA of a sphere = 4pi(radius)^2 SA = 4(3.14)2^2 SA = 50.24
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 any sphere is (4 pi) x (radius)2 So the surface area of this particular sphere is (4 pi) x (10)2 .
Surface area of a sphere = 4*pi*radius^2

Surface area of a sphere = 4*pi*radius2 For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere = 4*pi*(outer radius)2 - 4*pi*(inner radius)2 = 4*pi*[ (outer radius)2 - (inner radius)2 ]
SA of a sphere = 4pi(radius)^2 SA = 4(3.14)2^2 SA = 50.24
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 formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7cm, we get 4π(7)^2 = 4π(49) = 196π. Therefore, the surface area of a sphere with a radius of 7cm is 196π square centimeters.
The surface area of any sphere is (4 pi) x (radius)2 So the surface area of this particular sphere is (4 pi) x (10)2 .

Surface area of a sphere = 4*pi*radius^2
If the radius of a sphere is doubled, the surface area increases by (2)2 = 4 times, and the volume increases by (2)3 = 8 times.
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 4.75 is about 283.5 units2
No, if the radius of a sphere doubles, its surface area increases by a factor of 4, not simply doubling. The surface area of a sphere is proportional to the square of the radius.
