Question

radius 8 cm and height 15 cm.
Use 3.14 for π

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 \( r = 8 \) cm
- Height \( h = 15 \) cm
- Use \( \pi \approx 3.14 \)

Now, substitute the values into the formula:

\[
V = 3.14 \times (8)^2 \times 15
\]

Calculating \( (8)^2 \):

\[
(8)^2 = 64
\]

Now substitute back into the volume formula:

\[
V = 3.14 \times 64 \times 15
\]

Calculating \( 64 \times 15 \):

\[
64 \times 15 = 960
\]

Now substitute that back into the volume formula:

\[
V = 3.14 \times 960
\]

Calculating \( 3.14 \times 960 \):

\[
V = 3008.64 \, \text{cm}^3
\]

So, the volume of the cylinder is approximately \( 3008.64 \) cm³.
