Question

To calculate the volume of this cylinder, you will need to know:

1) the blank of the base (B)

2) the blank of this cylinder

Prism or cylinder v = Bh

Answer 1

To calculate the volume of a cylinder, you need the following information:

1. **Area of the base (B)**: This is typically the area of a circle for a cylinder, which can be calculated using the formula \( B = \pi r^2 \), where \( r \) is the radius of the base.

2. **Height of the cylinder (h)**: This is the vertical distance from the base to the top of the cylinder.

Using the formula for the volume of a prism or cylinder, you can calculate the volume (V) of the cylinder as:

\[ V = B \times h \]

So, if you know the radius of the base and the height of the cylinder, you can find the volume by first calculating the area of the base and then using it in the volume formula.

### Example:
- If the radius of the base \( r = 3 \) units and the height \( h = 5 \) units:
1. Calculate the area of the base:
\[
B = \pi r^2 = \pi (3^2) = 9\pi \text{ square units}
\]
2. Calculate the volume:
\[
V = B \times h = 9\pi \times 5 = 45\pi \text{ cubic units}
\]

So, the volume of the cylinder would be approximately \( 141.37 \) cubic units (using \( \pi \approx 3.14 \)).
