Question: A glaciologist models a cross-section of a glacier as a right triangle, where the hypotenuse represents the slope surface of length $z$, and the inscribed circle has radius $c$. If the ratio of the area of the circle to the area of the triangle is $\frac\pi c^2\frac12ab$, express this ratio in terms of $z$ and $c$. - go-checkin.com
