To find the volume \( V \) of a cylinder, you can use the formula:
\[
V = \pi r^2 h
\]
where \( r \) is the radius and \( h \) is the height. Given that \( r = 19 \) and \( h = 15 \) and using \( \pi \approx 3.14 \):
1. Calculate \( r^2 \):
\[
r^2 = 19^2 = 361
\]
2. Substitute \( r^2 \) and \( h \) into the volume formula:
\[
V = 3.14 \times 361 \times 15
\]
3. First, calculate \( 361 \times 15 \):
\[
361 \times 15 = 5415
\]
4. Now multiply by \( 3.14 \):
\[
V = 3.14 \times 5415 \approx 16900.1
\]
Therefore, the volume of the cylinder is approximately **16900.10** when rounded to the nearest hundredth.
