Question 600648: Hello, I need some help please! I have a composite word problem. It states: volume of a cylinder. The volume V of a right circular cylinder of height h and radius r is V= the pie symbol, r^2h. If the height is twice the radius, express the volume V as a function of r.

Replace 'h' with '2r' (since the height is twice the radius)

So the volume is now
