Question:

Find the equation of the circle with centre (–2, 3) and radius 4

Answer:

The equation of a circle with centre (h, k) and radius r is given as

(x­ – h)2 + (y ­– k)2 = r2

It is given that centre (h, k) = (–2, 3) and radius (r) = 4.

Therefore, the equation of the circle is

(x + 2)2 + (y – 3)2 = (4)2

x2 + 4x + 4 + y2 – 6y + 9 = 16

x2 + y2 + 4x – 6y – 3 = 0
