WebExample 1: Center Of A Circle From An Equation In Standard Form. Let’s say we want to find the center of the circle given by the equation (x – 2) 2 + (y + 4) 2 = 9; Comparing this to the standard form above, we can see that a = 2 and b = -4 (watch out for those negative signs: y – (-4) is the same as y + 4). WebFeb 27, 2024 · Center of Circle Formula. If the center is at (a, b) and radius is ‘r’ then the center of the circle formula is as follows: ( x − a) 2 + ( y − b) 2 = r 2. Here (x,y) is an …
