The surface area of every sphere is (4 pi) times (the radius squared).Knowing that, you can find the surface area of not only the one you'reasking about right now, but of every sphere that ever was, is, or will be !
The surface area of a sphere with radius 6 is: 452 square units.
The surface area of a sphere with a radius of 7cm is about 615.8cm2
The surface area of a sphere with a radius of 42cm is about 22,167cm2
Surface area of a sphere = 4*pi*radius2 Area = 49*pi square units

Surface area of a sphere = 4*pi*radius2
Surface area of a sphere = 4*pi*radius squared
Surface area of a sphere = 4*p*radius2 4*pi*radius2 = 2916 Divide both sides by 4*pi: radius2 = 232.047907 Square root both sides: radius = 15.23311875 cm
Surface area is 188.5 units2
Surface area including the underneath of the hemisphere = pi*radius2 + 2*pi*radius2 Total surface area = 27pi square units
The surface area of a sphere is equal to 4 x Pi x radius2
The surface area is 1,385.4 cm2
Surface area = 4*Pi*radius2
The surface area of every sphere is (4 pi) times (the radius squared).Knowing that, you can find the surface area of not only the one you'reasking about right now, but of every sphere that ever was, is, or will be !
Surface area of a sphere = 4*pi*radius2 Surface area = 4*pi*42 => 201.0619298 Surface area of the sphere = 201 square units correct to three significant figures.
