Answer:
$397.90
Step-by-step explanation:
We have to calculate the cost to fill the drum with oil.
The formula to get the volume of the drum is V = πr²h
V = 3.14×(1.2)²×4 = 18.09 feet³
Now, find the cost of oil to fill the drum:
Cost = Volume × cost = 18.09×22 = $397.90
Well, first we should calculate just how much volume the drum can carry. The formula we should use is πr^2(h): π((1.2 ft)^2)(4 ft) π(1.44 ft^2)(4 ft) 5.76π ft^3 ≈ 18.1 ft^3 Thus is costs: $22 * 18.1 ft^3 $398.2
