Answer:
5 sides
Step-by-step explanation:
The quickest way to answer this is to use the fact the exterior angles of a polygon add to 360.
If the interior angles are each 108, then the exterior angles are each 180 - 108 = 72. (using the fact that the Interior angle + exterior angle adds to 180)
Next, we just work out 360 ÷ 72 = 5.
So the polygon must have 5 angles, and therefore 5 sides.
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!
