When i thought the problems couldnt get harder…help?
here’s the very last math problem that i need help with I seriously have NO idea how to do this could someone explain? thank you 🙂
A swimming pool has to be drained for maintenance. The pool is shaped like a cylinder with a diameter of 14m and a depth of 2m. If the water is pumped out of the pool at the rate of 17m^3 per hour, how many hours does it take to empty the pool?
(the 17m^3 means 17m to the 3 power)
The volume of the cylinder is equal to the area of the surface multiplied by the depth of the cylinder.
The area of the surface is calculated with the formula πr^2 (Pi x radius squared).
Once you have calculated the volume in cubic meters, divide by 17 to get the number of hours it takes to empty the pool.
