Step by Step Solution
Step 1
The picture below shows the cylinder with the radius 4 inches and height h.
Step 2
Since the value of the volume and radius are given, we substitute V with 64, r with 4 and π with 3.14 into the formula as shown:
Step 3
Now, we have 502.4 = 50.24h. We can find h by dividing both sides of the equation by 50.24. This is shown below:
Step 4
Now, the calculated number 10, has no meaning until we include the unit for it. Since radius is in unit inch, the unit for h will be inch. Hence:
h = 10 in
Step 5
Therefore, the answer is B.
