The Archery board has 5 concentric ring of equal thickness and the blue ring is the central ring.
So if we take the thickness of each ring as 1 unit then using the formula for area of a circle, A = (pi) * r^2, the total area of the board is given by (pi)*5^2 which is 25pi.
To find the area of the blue annulus we can think of it as a circle with a circular hole cut in the middle so the area is (pi)*3^2 - (pi)*2^2. Which is 9pi - 4pi equal to 5pi.
So if the blue area is 5pi and the total area is 25pi then 1/5 or 20% of the board is blue.
