To find the volume of a cylinder, you can use the formula:

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

where:

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

Given:

  • Radius \( r = 5 \) centimeters,
  • Height \( h = 15 \) centimeters,
  • \( \pi \approx 3.14 \).

Now, substitute the values into the formula:

\[ V = 3.14 \times (5)^2 \times 15 \]

First, calculate \( (5)^2 \):

\[ (5)^2 = 25 \]

Now, substitute this back into the volume formula:

\[ V = 3.14 \times 25 \times 15 \]

Next, calculate \( 25 \times 15 \):

\[ 25 \times 15 = 375 \]

Now substitute this into the volume equation:

\[ V = 3.14 \times 375 \]

Finally, calculate \( 3.14 \times 375 \):

\[ V = 1177.5 \]

Thus, the volume of the cylinder is:

1177.5 cubic centimeters.

The correct response is:

1177.5 cubic centimeters.
