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.
:
Find the volume of the pool (r = half the diameter)
V = {{{pi*r^2*h}}}
V = {{{pi*8^2*1.7}}}
V = 341.8 cu/m
:
Find the time to pump this volume of water out
t = {{{341.8/13}}}
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
