Today i am solving the ncert class 10 solution of chapter surface areas and volumes . Find the best solution of the exercise 13.3 question number 9. Give me easiest solution of this question also give me the best solution of this question.A farmer connects a pipe of internal diameter 20 cm from a canal into a cylindrical tank in her field, which is 10 m in diameter and 2 m deep. If water flows through the pipe at the rate of 3 km/h, in how much time will the tank be filled?

Consider the following diagram-
Volume of water that flows in t minutes from pipe = t×0.5π m3
Volume of water that flows in t minutes from pipe = t×0.5π m3
Radius (r2) of circular end of cylindrical tank =10/2 = 5 m
Depth (h2) of cylindrical tank = 2 m
Let the tank be filled completely in t minutes.
Volume of water filled in tank in t minutes is equal to the volume of water flowed in t minutes from the pipe.
Volume of water that flows in t minutes from pipe = Volume of water in tank
t×0.5π = π×r22×h2
Or, t = 100 minutes
