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

### Asked by Topperlearning User | 30th Apr, 2014, 11:08: AM

Expert Answer:

Equation of a circle when the centre and radius are given is (x - h)^{2} + (y - k)^{2} = r^{2}.

Hence h = -2, k = 3 and r = 4.

(x + 2)^{2} + (y - 3)^{2} = 4^{2}

(x + 2)^{2} + (y - 3)^{2} = 16.
