Question

For the given equation, find the center and radius of the circle x^2 + ( y + 5 )^2 = 25 . What point is the center at ?

Answer 1

Center: ( − 5 , 2 )

Radius: 5

Explanation:

on edge

Answer 2

(0,-5)

Explanation:

The vertex form of the equation of a circle is
`(x-h)^2 + (y-k)^2 = r^2` where (h,k) is the center of the circle and r is the radius. This means that for the equation
`x^2 + (y+5)^2 = 25` the center is (0,-5).
