Answer:

r = 8

Step-by-step explanation:

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

We have the equation:

[tex]x^2+y^2=64\\\\(x-0)^2+(y-0)^2=8^2[/tex]

Therefore the center is (0, 0) and the radius r = 8

Answer:

The circles radius is 8

Step-by-step explanation:

It is 8 because that's what they say it is
