    First we write equation for circle that consist coordinates of the center and it consists radius. Equation goes like this:

    (x-x1) ^2 + (y-y1) ^2 = r^2

    x1 and y1 are coordinates of the center. since the circle's center is at coordinate start that means that (x1, y1) = (0,0)

    that means that 64 on the right side of given equation is r^2

    r^2 = 64

    r = 8

    Answer is 8
