Question

I need to know if it’s a, b, c or d

Answer 1

The general equation of a circle is

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

Here, (h,k) is the center of the circle and r is the radius of the circle.

change the given equation into the general form as follows:

`(x-0)^2+(y-0)^2=5^2`

So, the center is (0,0) and the radius is r = 5.
