WebFree Circle calculator - Calculate circle area, center, radius and circumference step-by-step WebThe standard form of the equation of the circle is given by, x-h 2 + y-k 2 = r 2. Where (h, k) is the center of the circle and r is the radius. Comparing the given equation with the standard form, we get: h = 3, k = 5 and r 2 = 25. Solve the equation r 2 = 25. r 2 = 25 r = ± 25 = ± 5. Here r is the radius of the circle which can not be ...
