Intersection of two circles First Circle x y radius To subscribe to this RSS feed, copy and paste this URL into your RSS reader. While it is now known that this is impossible, it was not until 1880 that Ferdinand von Lindemann presented a proof that is transcendental, which put an end to all efforts to "square the circle." For a simulation, I need to be able to calculate the radius $r$ of a circle $C$, knowing only two points on its circumference, $P_1$ and $P_2$, as well as the distance between them ($a$) and how much of the whole circumference $c$ is in the arc between those two points ($\frac{c}{x}$, where $x$ is known and $\geq 1$). Assuming that your $R$ is the radius, one can calculate $R=\frac{1}{2}*a*csc(\frac{a}{2})$ to obtain it, correct? 1 Im trying to find radius of given circle below and its center coordinates. Yep.
