Question

Find the equation of the circle with centre at (-3,-2) and radius 6​

Answer 1

Step-by-step explanation:

The general form of the equation of a circle is: (x – h)2 + (y – k)2 = r2 …..(1) Where, r is the radius of the circle and (h, k) is the centre of the circle. Here, r = 6, h = -3 and k = -2 Equation (1) ⇒ (x + 3)2 + (y + 2)2 = 62 or (x + 3)2 + (y + 2)2 = 36 or x2 + y2 + 6x + 4y – 23 = 0 Which is the required equation.Read more on Sarthaks.com - https://www.sarthaks.com/810917/find-the-equation-of-a-circle-with-centre-3-2-and-radius-6
