cool problem
I would do this as the ratio of area of band B to the area of the board .
the radius of the board is 3′ radius center 1′ and band a and b each one foot
so area is pi * r^2 = pi * 3^2 = 9 * pi
area of band b is area of board – area of center and band a
area a = pi * 2^2 = 4* pi
so area of bandd b is pi(9-4) = pi *5
band b as a percentage of board is 5pi/9pi *100/1
500 * pi / 9 * pi =500/9 = 55.5555 %
I think thats right , check the maths
