Calculate the Radius of a Circle WebDiameter: the largest distance between any two points on a circle; by this definition, the diameter of the circle will always pass through the center of the circle. We know that the arclength $s$ between the two points is given by $s = 2\pi r/x$, where $x$ is known. Parametric equation of a circle WebThe radius is any line segment from the center of the circle to any point on its circumference. WebWell, the equation of a circle takes the form: ( x h) 2 + ( y k) 2 = r 2 where h,k are the coordinates of the center of the circle, and r is the radius. A bit of theory can be found below the calculator. In this case, r r is the distance between (2,7) ( 2, 7) and (3,8) ( - 3, 8). Circle Calculator Solving for $y_2$, we have Then, using the formula from the first answer, we have: $$r \sin\left(\frac{\alpha}{2}\right) = \frac{a}{2} $$, $$r = \frac{\tfrac{1}{2}a} {\sin\tfrac{1}{2}\alpha } = \tfrac{1}{2}a\,\mathrm{cosec}\tfrac{1}{2}\alpha $$, $$r = \frac{1}{2}a\,\mathrm{cosec}\left(\frac{\pi}{x}\right)$$.
