# a cross sectional area of a circular duct is 226.865 square

a cross sectional area of a circular duct is 226.865 square inches. what would be the diameter of the duct?

I googled this. Couldn't find my Mathmatice for plumbers and pipefitters book LOL

Set: The diameter is x
then 3.14*x2=226.865
x=2.925

best i can do. ill opt out if you like

Cant give you the answer but pi*R sq =3.142*Radius.squared gives square area with a given radius, so work it back, do it in mm the convert to inches so much easier, Rick
