Description

### Functions
>Write functions that will calculate and return the following:

– `sphere_volume(radius)`


Where r is the radius

—
– `sphere_surface(radius)`


where r = radius of sphere

—
– `cylinder_volume(radius,height)`


where r = radius of sphere and h = height

—
– `cylinder_surface(radius,height)`


—
– `cone_volume(radius,height)`


Where r = radius of base of cone , h = height of the cone (perpendicular to base)

—
– `cone_surface(radius,height)`


Where l = slant height of a right circular cone
