The surface area of a polyhedron can be calculated by first calculating the area of each of its polygonal surfaces and adding these together.The surface area of some curved solids (sphere, cylinder, cone) can be calculated from formula but for most curved solids are more complicated and require integration.
Surface area of a sphere = 4*pi*radius squared
2(pi)(r)(h)=the area of the curved surface
Surface area = 4*Pi*radius2
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.
To find the surface area of a hemisphere, you can use the formula: SA = 2πr^2, where r is the radius of the hemisphere. This formula takes into account the curved surface area of the hemisphere.

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.
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
Surface area of a sphere = 4*pi*radius2 square units
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
