find the volume of the cylinder.- use 3.14 for pi

1 answer

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

\[ \text{Volume} = \pi r^2 h \]

where:

  • \( r \) is the radius of the cylinder,
  • \( h \) is the height of the cylinder,
  • \( \pi \) is approximately 3.14.

From the information provided:

  • The height \( h \) of the cylinder is 8 cm.
  • The diameter of the cylinder is given as 6 cm, which means the radius \( r \) is half of that:

\[ r = \frac{6 \text{ cm}}{2} = 3 \text{ cm}. \]

Now, substitute the values into the volume formula:

\[ \text{Volume} = 3.14 \times (3 \text{ cm})^2 \times 8 \text{ cm}. \]

First, calculate \( (3 \text{ cm})^2 \):

\[ (3 \text{ cm})^2 = 9 \text{ cm}^2. \]

Now plug this back into the volume formula:

\[ \text{Volume} = 3.14 \times 9 \text{ cm}^2 \times 8 \text{ cm} = 3.14 \times 72 \text{ cm}^3. \]

Now, perform the multiplication:

\[ 3.14 \times 72 = 226.08 \text{ cm}^3. \]

Thus, the volume of the cylinder is:

\[ \text{Volume} \approx 226.08 \text{ cm}^3. \]
