The answer is 36π or approximately 113.1 cm.
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 ]

The surface area of a 14-inch sphere is 615.75 square inches.The formula for the surface area of a sphere is 4*pi*r2 where r=radius
2,157.7 square meters.
Surface area = 201.06 meters2
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 .
615.75216 m2
Surface area = 4*pi*22 = 50.26548246 or about 50 square meters
Area = 4 x pi x radius squaredAnswer is 61575.2m2
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
-- You have to ask somebody for the radius of the sphere, in meters. If they tell you the diameter instead, then the radius is 1/2 of the diameter, in meters. -- Multiply (4) times (pi) times (the radius)2 . That's the surface area of the sphere, in square meters. -- Round the answer to the nearest square meter.
100 x pi m2
Volume = 113.097 m3 Surface area = 113.097 m2
Surface area = 4*pi*72 = 615.752 square meters to 3 decimal places
The suface area of a sphere with a radius of 7 meters is 615.75m2
The surface area of a sphere with a radius of 5m is 314.2m2
