i am not sure what you mean by 7ft, but i am going to assume that the radius of the sphere is 7 feet.

the volume of a sphere - 4/3 * π * r^3

plugging in the 7 feet as the radius and 3.14 as π, you get:

4/3 * 3.14 * 343

which equals

≈ **1436.03**

i hope this helped! please correct me if i'm wrong :)
