Answer:
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
