Figure 4.1.10 Relationship between the Circumference and Diameter of a Circle

Calculating Diameter of a Cylindrical Storage Facility Using Circumference

The circumference of a below grade, concrete cylindrical storage facility is measured as 124 m. Based on this information, the diameter of this manure storage is: Diameter = Circumference ÷ π

Diameter of a cylindrical storage facility (m) = 124 m ÷ 3.1416

= 39.5 m is the diameter of the cylindrical storage facility

Knowing the facility dimensions, volume can be estimated using the following calculation:

Manure volume = height of manure x (diameter 2 ) x 0.785
