First what we must do is find the radius. This can be easily found because we know that the radius is always half of the diameter so 23/2. This gives us a radius of 11.5 yards. Now, we put it through the standard formula for a circle π*r*r or π*r^2 (r being the radius). Here is the equation you now have, π*11.5^2 which gives us a total area of 415.47 or 132.25π.
