Question

A farmer connects a pipe of internal diameter 20 cm from a cannal into a cylindrical tank in his field, which is 10 m in diameter and 2m deep. If water flows through the pipe at the rate of 4 km/h, in how much time will the tank be filled?

Answer 1

Answer:

Step-by-step explanation:

r=10 cm

R=500cm

h=200cm

volume of water flows in 1 hr =pie×10×10×300000(cmcube)

volume of cylindrical tank =pie×500×500×200

time taken to be fill the tank=volume of cylindrical tank÷volume of water flow in 1 hr

=(pie×500×500×200)÷pie×10×10×300000

=(5÷3)hr

=(5÷3)×60

=100min..
