The area of the washer will be the area of the smaller circle SUBTRACTED from the area of the larger circle.
Area of a circle = pi * r^2 where r is your radius (which is half the diameter).
Larger circle area = pi *(diameter/2) ^2.
Smaller circle area = pi * (13.2/2)^2 = pi * 6.6^2 = 136.8484....
So...the area of the washer = larger circle area - 136.4848...
