How to find the radius of a sphere</a>

Before solving the problem of finding the radius of a sphereDo I enter a definition of objects? Sphere and sphere. From the course of stereometry it is known that a sphere is a surface that consists of points of space equidistant from a given point. This point is called the center of the sphere, and the distance to which the points of the sphere are distant from its center,? Radius of the sphere and is denoted by R. The body bounded by the surface of a sphere is called a sphere.

The method for determining the radius of a sphere depends on the available initial data.

Instructions

    1

Let the sphere be given and the area of ​​its surface known. Then, using the formula to calculate the surface area of ​​a sphere, you can calculate its radius:
R = v (4? П / S), where S is the surface area of ​​the sphere, П = 3,14.

If the volume of the sphere that limits the sphere is known, then the radius can be found by the volume formula:
R = (3? V / 4? П) ^ 1/3, where V is the volume of the sphere, П = 3,14.
