# How to find the equation of a circle given the center and radius

The radius of a circle is a positive numerical value. General equation for a circle: (x−h)2 +(y−k)2 =R2 ( x − h) 2 + ( y − k) 2 = R 2, where (h,k) ( h, k) are the coordinates of the  Circle equation calculator

The standard equation of a circle is given by: (x - h)² + (y - k)² = r² ———————— (1) Where (h, k) is the coordinates of center of the circle and r is the radius of the circle. In this question, circle
