A drum of oil has a height of 4 ft and a radius of 1.2 ft. The oil cost $22 per ft³.
iogann1982 [59]
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!

Question about a rational expression
sesenic [268]
-9=6/v

You have to multiply v both sides because

If you multiply by 6, 6/v x 6 = 36/v, that’s why it don’t work.

Answer:
-9=6/v
-9v=6
v=-6/9
v=-2/3

Find the volume of the triangular prism
juin [17]

Answer:

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.
