It takes your garden hose 19 seconds to fill your 2-gallon watering can. how long in hours will it take to fill a circular inflatable pool 12 feet in diameter and 3.5 feet deep?

Time taken to fill the pool = 7.81 hours

Step-by-step explanation:

We are given that it takes 19 seconds to fill 2 gallons. Therefore, we can use cross multiplication to know how long will it take to fill one gallon as follows :

Time taken to fill 2 gallons of tank = 19 seconds

Therefore, it takes 9.5 seconds to fill one gallon of water.

One gallon is equivalent to 0.133681 cubic feet

Therefore, it takes 9.5 seconds to fill 0.133681 cubic feet

Now, to find Volume of the pool :

radius of pool = 6 ft

volume of pool = pi × (radius)² × height

volume of pool = 3.14 × 6² × 3.5 

volume of pool = 395.64 cubic feet

Time taken to fill 0.133681 cubic feet of water = 9.5 sec

Hence, Time taken to fill the pool = 7.81 hours

one set of data has more variation than the other. hope this !

there were a lot of them but the first one to pop up on a google search was bts
