The volume of a right circular cylinder is 27,355.68 mm. 3 . Find the height of the cylinder if the radius is 22 mm. Use 3.14 for π .(1 point)

1 answer

To find the height of a right circular cylinder, we can use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

Where:

  • \(V\) is the volume,
  • \(r\) is the radius,
  • \(h\) is the height, and
  • \(\pi\) is approximately 3.14.

Given:

  • \(V = 27,355.68 , \text{mm}^3\)
  • \(r = 22 , \text{mm}\)
  • \(\pi = 3.14\)

We need to find the height \(h\). Rearranging the formula to solve for \(h\):

\[ h = \frac{V}{\pi r^2} \]

Now we will calculate \(r^2\):

\[ r^2 = 22^2 = 484 , \text{mm}^2 \]

Next, plug in the values:

\[ h = \frac{27355.68}{3.14 \times 484} \]

Calculating \(3.14 \times 484\):

\[ 3.14 \times 484 = 1519.76 \]

Now substitute this back into the equation for \(h\):

\[ h = \frac{27355.68}{1519.76} \approx 17.98 , \text{mm} \]

Thus, the height of the cylinder is approximately 17.98 mm.
