Question

Hal has a steel barrel with a diameter of 6 feet that can be filled to a depth of 4.6 feet with oil. What is the volume of the barrel?

Use = 3.14
OA 93.696 cubic feet
OB. 154.116 cubic feet
OC. 129.996 cubic feet
OD 124.2 cubic feet

Answer 1

129.996 cubic feet

Explanation:

Assuming that the barrel is a perfect cylinder, we can use the formula to find the volume:

`\pi(r)^2(h)`

First, we have to find the radius, which is:

D = 2r

So the radius is 3 feet, since it is half of the diameter. Then, we plug in the values.

`3.14(3)^2(4.6)`

Now, we solve. Exponents are first...

3.14(9)(4.6)

Now multiply left to right.

28.26(4.6)

129.996 cubic feet

Therefore, the barrel can hold 129.996 cubic feet of oil. Hope this helps you!
