Simply multiply the equation by 6, in order to get rid of the denominators:
We have to rearrange the equation in the form
So that is the radius, and
will be the diamater. We have to complete the squares: rewrite the equation as
You can see that is the beginning of
Similarly, is the beginning of
So, if we add 16 and 9 to both sides, the equation becomes
So, now we know that , and thus the radius is 13, so the diameter is 26.
