Answer: a) 1791 seconds
b) 29701 seconds
Step-by-step explanation:
1 us gallon = 0.134 cubic foot
It takes your garden hose 20 seconds to fill your 2-gallon watering can. Converting 2 gallons to cubic foot, it becomes
2 × 0.134 = 0.268 cubic foot
a) The volume of inflatable pool measuring 3 feet wide, 8 feet long, and 1 foot deep.
Volume = 3 × 8 × 1 = 24 cubic feet
If 0.268 cubic foot = 20 seconds
24 cubic feet = (24 × 20)/0.268
= 1791 seconds
b) Volume of a cylinder is πr²h
Diameter = 13 feet
Radius = diameter/2 = 13/2 = 6.5
Volume of the circular pool is
3.14 × 6.5² × 3 = 397.995 cubic feet
If 0.268 cubic foot = 20 seconds
397.995 cubic feet = (397.995 × 20)/0.268
= 29701 seconds
