Question

find the equation of the circle with centre c and r where c=(5/2, -4/3) , r = 6​

Answer 1

Answer:

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 = 5, h = 2 and k = 4 Equation (1) ⇒ (x – 2)2 + (y – 4)2 = 52 or (x – 2)2 + (y – 4)2 = 25 or x2 + y2 – 4x – 8y – 5 = 0 Which is the required equation.Read more on Sarthaks.com - https://www.sarthaks.com/810908/find-the-equation-of-a-circle-with-centre-2-4-and-radius-5
