The equation of a circle is represented as:
[tex](x-h)^2+(y-k)^2=r^2[/tex]Here, (h, k) represents the center of the circle, and 'r' represents the radius of the circle.
According to given parameters:
(h, k) = (0, 0)
or
h = 0
k = 0
and
r = 8
Now, put all the values in the above equation to get the equation of the circle.
[tex](x-0)^2+(y-0)^2=8^2[/tex][tex]x^2+y^2=64[/tex]Hence, the equation of circle is x^2 + y^2 = 64.
