A large pipe has a diameter of 9.8×10^2cm.Water flows in the pipe at a speed of 5m s^-1.Find the volume in m^3,of water that flows out from the pipe every second,correct to 2 significant fogures.[Take pai as 3.142]
Answered by Steve
9.8x10^2 cm = 980cm = 9.8m
So, the rate of flow is

pi*4.9^2 m^2 * 5m/s = 377 m^3/s
