A swimming pool has to be drained for maintenance. The pool is shaped like a cylinder with a diameter of 10m and a depth of 1.4 m. Suppose water is pumped out of the pool at a rate of 18 m3 per hour. If the pool starts completely full, how many hours will it take to empty the pool?

10 hours-around that number

Step-by-step explanation:

(3.14)*52*1.4 m3 = 109.9 m3 of water.-area

at the rate of 18m3 per hour

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
