Welcome to AskIITians
Given that:
Radius, r = 4, and center (h, k) = (-2, 3).
We know that the equation of a circle with centre (h, k) and radius r is given as
(x – h)^2+ (y – k)^2= r^2….(1)
Now, substitute the radius and center values in (1), we get
Therefore, the equation of the circle is
(x + 2)^2+ (y – 3)^2= (4)^2
x^2+ 4x + 4 + y^2– 6y + 9 = 16
Now, simplify the above equation, we get:
x^2+ y^2+ 4x – 6y – 3 = 0
Thus, the equation of a circle with center (-2, 3) and radius 4 is x^2+ y^2+ 4x – 6y – 3 = 0
