Question

Find the volume of the cylinder below. Use the approximation 3.14 for pi.
height=15
radius=5

Answer 1

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,
- \( \pi \) is approximately \( 3.14 \).

Given:
- Radius \( r = 5 \)
- Height \( h = 15 \)

Substituting the values into the formula:

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

Calculating \( 5^2 \):

\[
5^2 = 25
\]

Now substituting that back into the formula:

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

Calculating \( 25 \times 15 \):

\[
25 \times 15 = 375
\]

Now substituting that back:

\[
V = 3.14 \times 375
\]

Calculating \( 3.14 \times 375 \):

\[
V = 1177.5
\]

Thus, the volume of the cylinder is:

\[
\boxed{1177.5}
\]
