I was doing some optimization questions to get ready for a test. I came across one that stumped me. The question was "Find the dimensions of the isosceles triangle of the largest area that can be inscribed in a circle of radius r".(adsbygoogle = window.adsbygoogle || []).push({});

My approach was:

let y be the base of triangle

let x be the two equal sides of triange.

A(t) = (bh)/2

= (y*(x^2-(y/2)^2)^1/2))/2

I cant find the equation to relate the radius to the area. help?
