To be more precise, with your method, the answer is $$\frac{\sqrt{(y_1-y_0)^2+(x_1-x_0)^2}*\sin(\frac{\pi}{2}-\tan^{-1}\left(\frac{|y1-y0|}{|x_1-x_0|}\right)}{\sin\left(\pi-2\left(\frac{\pi}{2}-\tan^{-1}\left({|y1-y0|}\over{|x_1-x_0|}\right)\right)\right)}$$. Circle Radius Calculator Then, using the formula from the first answer, we have: $$r \sin\left(\frac{\alpha}{2}\right) = \frac{a}{2} $$, $$r = \frac{\tfrac{1}{2}a} {\sin\tfrac{1}{2}\alpha } = \tfrac{1}{2}a\,\mathrm{cosec}\tfrac{1}{2}\alpha $$, $$r = \frac{1}{2}a\,\mathrm{cosec}\left(\frac{\pi}{x}\right)$$. It is also a transcendental number, meaning that it is not the root of any non-zero polynomial that has rational coefficients. Select the circle equation for which you have the values. This was a process that involved attempting to construct a square with the same area as a given circle within a finite number of steps while only using a compass and straightedge. In addition, we can use the center and one point on the circle to find the radius. Also $R \cdot sin({\alpha \over 2}) = {a \over 2}$, it is also pretty obviously. Solving for $y_2$, we have This is a nice, elegant solution and I would accept it if I could accept two answers.
