I have solved the first one. Hope this helps
Volume of a Cylinder (Drum) = πr²h
Substitute the known values,
v = 3.14 * (1.2)² * 4
v = 18.09 Ft³
Now, price for 1 Ft³ = $22
So, for 18.09 Ft³ would be: 22 * 18.09 = $397.9
In short, Your Answer would be: $397.9
Hope this helps!
I do not see anything wrong with it
