circle area = pi * diameter^2 / 4 annulus area = outer circle area - inner circle area = (outer^2 - inner^2)*pi/4 diameter of circle equivalent to annulus area = sqrt(outer^2 - inner^2)
If given diameter is the true outer diameter, then that of a circle equivalent to the annulus area is: implied inner outer ==> equivalent diameter 5.182 7.288 **5.125** difference of squares
area 21.090 41.716 20.626
If given diameter is the that of a circle equivalent to the annulus area, then true outer diameter is: implied inner equivalent ==> outer Geoffrey Glass confirmed 7.288 was an equivalent diameter. diameter 5.182 7.288 **8.942** sum of squares
