A barrel in the shape of a cylinder has a height of 4.5 feet and a diameter of 6 feet. The barrel is filled with oil to 6 inches from the top of the barrel. What is the volume of oil in a barrel?

i got it wrong but the guy who says its 113.04 ft^2 is right

The volume of oil in a barrel is 113.04ft³

Step-by-step explanation:

To calculate the volume of a cylinder we have to use the following formula:

6in = 0.5ft

v = volume

h = height = 4.5ft  - 0.5in = 4ft

π = 3.14

r = radius = 6ft /2 = 3ft

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (3ft)²) * 4ft

v = (3.14 * 9ft²) * 4ft

v = 28.26ft² * 4ft

v = 113.04ft³

The volume of oil in a barrel is 113.04ft³

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.
