The formula for the surface area of a sphere is: 4 pi r 2
Half of a sphere
Surface area of a sphere = 4πr2
The formula for the surface area of a sphere is 4πr2. The formula for the volume of a sphere is 4/3πr3.
Formula for volume of a sphere = 4/3*pi*radius3 measured in cubic units.
The formula for calculating the surface area of a sphere is 4πr², where r is the radius of the sphere. This formula represents the area covered by the curved surface of the sphere.
Because a sphere is a 3 dimensional shape.
The formula for the surface area of a sphere is: 4 pi r 2
There is no single formula for volume. Some simple shapes, such as a cuboid, sphere, cone, pyramid, prism have relatively simple, but different formulae. Other shapes have more complicated formulae.
Half of a sphere
Surface area of a sphere = 4πr2
The formula for the surface area of a sphere is 4πr2. The formula for the volume of a sphere is 4/3πr3.
Formula for volume of a sphere = 4/3*pi*radius3 measured in cubic 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.
