What is the volume of this cylinder?




























Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.

r = 19 mm
h = 15 mm

1 answer

The volume \( V \) of a cylinder can be calculated using the formula:

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

Where:

  • \( r \) is the radius of the base of the cylinder,
  • \( h \) is the height of the cylinder.

Given:

  • \( r = 19 \) mm
  • \( h = 15 \) mm
  • Using \( \pi \approx 3.14 \)

Now, we can plug the values into the formula:

\[ V = 3.14 \times (19)^2 \times 15 \]

First, calculate \( (19)^2 \):

\[ (19)^2 = 361 \]

Now, substitute this back into the volume formula:

\[ V = 3.14 \times 361 \times 15 \]

Next, calculate \( 361 \times 15 \):

\[ 361 \times 15 = 5415 \]

Now, substitute this back into the volume formula:

\[ V = 3.14 \times 5415 \]

Finally, calculate \( 3.14 \times 5415 \):

\[ V \approx 17,004.1 \]

Rounding to the nearest hundredth, the volume of the cylinder is:

\[ \boxed{17004.10} \text{ mm}^3 \]
