I was given an answer to a question but what I really need are the steps to get there as I have other questions I need to answer the same way.
Solve the equation w=Cr^2 for r
I was given r=C/w
This equation is meant to figure out the weight of an object where C is a constant and r is the distance that the object is from the center of the earth.
My very next question asks me to substitute 100 pounds for an oject so if I don't get his right they will all be wrong.
Can anyone show me the steps?

w=c/r^2
r^2=C/w
r= sqrt (C/w)
