Question

a farmer connects A pipe of internal diameter 20cm from a Canal into a cylindrical tank in his field which is 10 metre in diameter and metre deep if water flows through the pipe at the rate of 3 km per hour in how much time will the tank be filled ​

Answer 1

Step-by-step explanation:

Convert the all the units into into metres or centimetres (cm in my case)

Equate the height of the Pipe with

$s = d \div t$

So, the height of the Pipe is

$(500 \div 6) \times t$

Where t is the time taken to fill the tank

then, equate the volumes of both the Pipe and thr Tank and solve for 't'
