Question

Figure below shows the cross section of a water channel consisting of rectangle and semi circle. Assuming that the channel is always full , calculate the volume of water discharged through it in one minute if water is flowing at the rate of 20 cm per second. Give your answer in cubic meters correct to one decimal.

  1. 0.34
  2. 0.3843
  3. 3.4
  4. 3.843

The correct answer is: 0.3843
