Question

A circle has its center at (-2, -3) and a radius of 3 units. What is the equation of the circle?

(x + 2)2 + (y - 3)2 = 9

(x + 2)2 + (y + 3)2 = 9

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

(x + 2)2 + (y + 3)2 = 3

Answer 1

lets centre of a circle is (a,b)
and radius c
then its eq is
(x-a)^2+(y-b)^2=c^2

Answer 2

thanks
