Answer:
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
