In mathematics the surface area of a Sphere formula is given as Where r is the fixed distance from the center point or we can call it the radius of Sphere. Add those two parts together and you have the formula for the surface area of a cylinder. The surface area of a sphere of radius r is.
AREA 4 p r ².
Just like a circle the size of a sphere is determined by its radius which is the distance from the center of the sphere to any point on its surface. If you know the surface area of a sphere it is possible to calculate the radius of the sphere by rearranging the surface area formula. This why it appears in nature so much such as water drops bubbles and planets. Surface area of a sphere 4pr2 square units.
