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

Asked by Topperlearning User | 30 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 = r2.

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

(x + 2)2 + (y - 3)2 = 42

    (x + 2)2 + (y - 3)2 = 16.
