Question

find the volume of the cylinder below use the approximation 3.14 for pi. radius 5 cm 15 cm

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, and \( h \) is the height.

Given:
- Radius \( r = 5 \) cm
- Height \( h = 15 \) cm
- Use \( \pi \approx 3.14 \)

Now, let's plug in the values:

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

Calculating \( (5)^2 \):

\[
(5)^2 = 25
\]

Now, substitute back into the volume formula:

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

Now calculate \( 25 \times 15 \):

\[
25 \times 15 = 375
\]

Now substitute that result into the equation:

\[
V = 3.14 \times 375
\]

Now we perform the final multiplication:

\[
V = 1177.5
\]

Thus, the volume of the cylinder is approximately \( 1177.5 \) cubic centimeters.
