[R] How to write a regression model for finding the radius of a cylinder given height and volume

[nivek]

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.  

cylinder.dat

Thank you for your help. This is not homework however and my difficulty is in
the fact that i cannot figure out how the declare a variable for the height
or the volume given a data set where the matrix is already formed. I have
looked on many sites for the is answer and it seems like it would be an easy
one. So for this problem the provided data column 2 is the height data and
column 1 is the volume. What command do I use to read those values and form
a vector. Thank you for your time.
