Question 255953: Can you please show me how to do this??
The height of a cylinder is 6 ft greater then the radius. The volume of a cylinder is given by the formula V=pi r^2 h. If the total volume of the cylinder is 60 ft^3, what is the approximate radius of the cylinder?

The height of a cylinder is 6 ft greater then the radius.
The volume of a cylinder is given by the formula V=pi r^2 h.
If the total volume of the cylinder is 60 ft^3, what is the approximate radius of the cylinder?
:

r^3 + 6r^2 = 19.1
:
r^3 + 6r^2 - 19.1 = 0
:
Graph this:

:
r ~ 1.6
:
:
Check that
=
= 61 ~ 60
