Remember that the equation of a circle in standard form is given by: (x – a)2 + (y – b)2 = r2. where (a, b) is the center of the circle and r is the radius of the circle. If we are given an
Given, Centre = (a, b) = (2, 3) Radius = r = 1. Standard form of circle equation is (x – a) 2 + (y – b) 2 = r 2. Substituting the values of centre and radius, (x – 2) 2 + (y – 3) 2 = 1 2. x 2 – 4x + 4 + y 2
