Question

X^2+(y+)4^2=64 khan academy

Answer 1

Answer: The center is 0,4

Explanation:

Use this form to determine the center and radius of the circle:

(

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

Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin:

r=8

h=0

k=4

The center of the cirle is found at (h,k): (0,4)

The radius is 8
