Question

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

Answer 1

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

Answer 2

@ganeshie8 Help please?

Answer 3

Equation of a circle with center (h, k) and radius r is
(x−h)2+(y−k)2=r2

Answer 4

yup
so substitute center(h,k)=(-2,-3)

Answer 5

How did you get the formula?
