mr.math · Answer

c is directly proportional to r means $c=kr$, what do you think k is in this case?

aroub · Answer

k?

mr.math · Answer

Yeah, Just compare it to the formula you've written above! k=...?

aroub · Answer

Yes I know! but you have 'π^2' I think it's different right?

mr.math · Answer

Well, the constant in the formula you wrote is $\pi^2$. I don't know what you mean by "it's different".
