The area of a sphere is 4 x pi x r2. "r" is the radius.
Surface area of a sphere = 4*pi*radius2
Surface area of a sphere = 4*pi*radius2 square units
Surface area of a sphere = 4*pi*radius squared
The area of a sphere is 4πr2.
Surface area of a sphere = 4 x (pi) x (radius)2
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 radius of the sphere is ~16.395 units.
The surface area of a sphere is equal to 4 x Pi x radius2
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.
Area of a sphere = (4pi/3) x (radius)3 Area of a prism depends on its shape, how many faces, etc.
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
The area of a sphere is given by the formula A = 4πr² A sphere with radius r has an area = 4πr² A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr² The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1 If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units.
