Question

A cylindrical pressure vessel has a height of 9 feet and a diameter of 6 feet. How much gas can the pressure vessel hold when full?

Answer 1

81
`The majority f math problems do not multiply pi`

Explanation:

Answer 2

Height of the cylindrical pressure vessel = 9 feet
Diameter of the cylindrical pressure vessel = 6 feet
Then
Radius of the cylindrical pressure vessel = (6/2) feet
= 3 feet
Then
Volume of the cylindrical pressure vessel = πr^2h
= 3.14 * (3)^2 * 9 cubic feet
= 3.14 * 9 * 9 cubic feet
= 254.34 cubic feet
So the amount of gas that the cylindrical pressure vessel can hold is 254.34 cubic feet. I hope the procedure is clear enough for you to understand.
