Finding the Volume of a Storage Bin I

### Volume Calculation for a Cylindrical Silo with a Conical Base

A fairly common shape for a dry-solids storage bin is a cylindrical silo with a conical collecting section at the base where the product is removed (see Figure 4.60).

#### Diagram Description
**Figure 4.60:** Storage silo.
- The diagram depicts a cylindrical silo with a conical base. 
- \( h_{\text{cone}} \) is the height of the conical section.
- \( \theta \) is the angle of the cone.
- \( R \) is the radius at the base of the cylindrical section.

#### Volume Calculation

To calculate the volume of the contents, you use the formula for a cone, as long as the height of the product, \( h \), is less than the height of the conical section, \( h_{\text{cone}} \).

\[ V = \frac{1}{3} \pi {r_h}^2 h \quad \text{if} \quad h < h_{\text{cone}} \]

(Equation 4.11)

Here, \( r_h \) is the radius at height \( h \) and can be calculated from \( h \) using trigonometry:

\[ r_h = h_{\text{cone}} \tan(\theta) \]

(Equation 4.12)

If the height of the stored product is greater than the height of the conical section, the equation for a cylinder must be added to the volume of the cone:

\[ V = \frac{1}{3} \pi R^2 h_{\text{cone}} + \pi R^2 (h - h_{\text{cone}}) \quad \text{if} \quad h > h_{\text{cone}} \]

(Equation 4.13)

If the height of the conical section is 3 meters, the radius of the cylindrical section is 2 meters, and the total height of the storage bin is 10 meters, what is the maximum volume of material that can be stored?
