    forming a regression model to solve for radius of a cylinder given height and volume

    Hello,
    Iím new to the programming language R and Iím trying to solve a simple problem for finding the radius of a cylinder given the height and volume. I've tried to included the data file but it says it is invalided type. Anyways the data file includes the height in cm is column 2 and volume in cm is in column 1. I know the equation needed is R=squrt(V/H(3.14)) were R=radius, V=volume and H=height. My question is how do I code this regression model in R. Any help is greatly appreciated.

    Think to the logarithms : 2*log(R) = log(V) - log(H)

    So is this the regression model for solving the radius? Given y=log(Vol) and x=log(ht) I have to find the model for regression of y on x.
