Question 697770: A swimming pool has to be drained for maintenance. The pool is shaped like a cylinder with a diameter of 16m and a depth of 1.7m. If the water is pumped out of the pool at the rate of 13m^3(cubed) per hour, how many hours does it take to empty the pool?
Use the value 3.14 for Pi , and round your answer to the nearest hour.

You can put this solution on YOUR website! A swimming pool has to be drained for maintenance.
The pool is shaped like a cylinder with a diameter of 16m and a depth of 1.7m.
If the water is pumped out of the pool at the rate of 13m^3(cubed) per hour,
how many hours does it take to empty the pool?
Use the value 3.14 for Pi , and round your answer to the nearest hour.
:
Find the volume of the pool (r = half the diameter)
V =
V =
V = 341.8 cu/m
:
Find the time to pump this volume of water out
t =
t = 26.3 ~ 26 hrs
:
:
Note: I used pi on the calc, you can recalculate it using 3.14, you will see it will still round out to 26 hrs
