help with this equation!!!?

Question

I need to find g(h) and g(r) using this equation, Im totally stuck it's been a few years since i took pre-calc.

pi r^2+(2/3) pi r^3

The equation is the volume of a cylinder and the volume of a hemisphere added together.

Please help! Thanks!

Okay so its not about solving the equation, as in I need to know the volume, but i have to set the equation equal to "h" and then take the same equation and set it equal to "r"

Answer 1

Your equation should read V = pi r^2h+(2/3) pi r^3

I do not understand the g(h) and g(r) business. Could you clarify what you are after?

The sphere is a function of r.
The cylinder is a function of r and h assuming r of cylinder and r of sphere are the same.
The total volme is a function of g and r.
