Question

Find the equation of a circle with its center at (5, -2) and a radius of 16.

(x - 5)2 + (y + 2)2 = 256
(x + 5)2 + (y - 2)2 = 256
(x - 5)2 + (y - 2)2 = 256
(x + 5)2 + (y + 2)2 = 256

Answer 1

(x - 5)2 + (y + 2)2 = 256

Explanation:

hello

Answer 2

The general form of equation of circle with radius r and centre (h,k) is given by

`(x-h)^2 +(y-k)^2 = r^2`

In the given question , h=5, k =-2 and r=16. Substituting these values in the given equation of circle, we will get

`(x-5)^2 +(y+2)^2 = 256`

So the correct option is the first option .
