Question

Find the equation of the circle whose center and radius are given.

center ( 7, -3), radius = √7

Answer 1

(x-7)^2 + (y+3)^2 = 7

Explanation:

The equation of a circle is

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-7)^2 + (y- -3)^2 = (sqrt(7))^2

(x-7)^2 + (y+3)^2 = 7
