Answer:
<h2>r = 8</h2>
Step-by-step explanation:
The standard form of an equation of a circle:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(h, k) - center
r - radius
We have the equation:
![x^2+y^2=64\\\\(x-0)^2+(y-0)^2=8^2](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D64%5C%5C%5C%5C%28x-0%29%5E2%2B%28y-0%29%5E2%3D8%5E2)
Therefore the center is (0, 0) and the radius r = 8
