Question

Given the center and radius, find equation of the circle​

Answer 1

Answer:

${ \sf{ {(x - 2)}^{2} + {(y + 8)}^{2} = 4}}$

Answer 2

Answer:

Center is (2, -8) and radius =2

h = 2 and k = -8

Filling in this equation:

(x -h)² + (y -k)² = radius²  we get:

(x - 2)^2 + (y--8)^2 = 2^2 which equals

(x-2)^2 + (y +8)^2 = 4
