The surface area of the sphere is 105 square inches what is the volume of the sphere use 3.14 for pi

The volume of the sphere is .

Step-by-step explanation:

A sphere is a 3-D figure in which all of the points in a plane are the same distance from a given point, the center of the sphere.                      

A sphere with radius r has a volume of

and a surface area of

To find the volume of the sphere we use the fact that the surface area of the sphere is 105 and we use it to find the radius.

The radius cannot be negative. Therefore,

Now, that we know the radius we can find the volume
