Best ResponseYou've already chosen the best response.0Perhaps that is the official formula to get the area of the circle instead of from the radius.

Best ResponseYou've already chosen the best response.0No, the volume of a circle is pi times radius squared. You can work out the area of the circle using this if you halve the diameter to get the radius.

Best ResponseYou've already chosen the best response.0I guess this sums up to (1cm)^2*pi=3.14cm^2=3.14m^2*10^3*2m/s=6.28*10^3m^3/s=rate of flow.
