I need to know how to figure out "r" in this picture from "R" and "h". It is some kind of proportion or integral i'm guessing, but I can;t think of it. "R" is the radius of a spherical tank. "r" is the radius of the water level (not the same as "R") "h" is the height of the water level. Here is the pic. The water level will be draining out, thats why I need to figure out a GENERAL proportion.(adsbygoogle = window.adsbygoogle || []).push({});

Can someone help me!
