    Since the area of a circle is related to the square of the radius, just square both radii. Then divide the smaller number by the larger number and multiply by 100. That gives you what percentage of the area of the large circle is the area of the small circle. Then subtract that percentage from 100%.

    5*5*3.14=78.5 4*4*3.14=50.24 50.24/78.5=.64 1-.64=.36 so 36%

    4^2 = 16 5^5 = 25 16/25 * 100 = 64% 100% = 64% = 36%
