Re-tried using your help... (pi)(0.19^2)V= 0.5m^3/306s (pi)(0.19^2)V= 0.016 V= 0.016/(pi)(0.19^2) V= 8 x 10^-4 ... i was incorrect
I did: Q=change in v/change in t = (500L)/(5.1m) = (500L)/ (306s) = 1.6 L/s convert > 1 L = 100 mL = 10^3 cm^3 = 10^-3 m^3... therefore I got 16 x 10^-4 v= Q/A = Q/(pi)(r^2) v = 16x10^-4/(pi)(0.0955)^2 = 0.017 i am incorrect though
