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

Equation of a circle: \((x - x_1)^2 + (y - y_1)^2 = r^2\)
Where \((x_1, y_1)\) is the center, \(r\) is the radius.

Use that.
