We have a policy of not doing your homework for you, but I can point you to a valuable resource for learning R http://cran.r-project.org/doc/contrib/Paradis-rdebuts_en.pdf. Your problem involves simple arithmetic. There is no regression problem unless you are trying to predict height from volume or volume from height (assuming that radius is constant).

Subject: [R] How to write a regression model for finding the radius of a cylinder given height and volume
Hello,
I’m new to R and I’m trying to solve a simple problem for finding the radius
of a cylinder given the height and volume. I’ve included the data file where
the height in cm is column 2 and volume is in column 1. I know the equation
needed is r= √(V/H(3.14)). My question is how do I code this regression
model in r. Any help is greatly appreciated.
