What formula is used to calculate the capacity in circular objects?

The formula for calculating the capacity of circular objects, specifically cylindrical ones, is based on the geometric properties of a cylinder. The correct choice involves multiplying the area of the circular base by the height of the object and then converting cubic feet to gallons for practical use.

In this formula, "Pi" represents the mathematical constant that is approximately 3.14, R stands for the radius of the circular base, and the height is taken into consideration to determine the total volume. The expression "Pi x R squared" calculates the area of the circular base, which is then multiplied by the height (H) to yield the volume in cubic feet. The final part, "7.48 gallon/ft cubed," is included to convert the calculated volume from cubic feet to gallons, making it practical for applications such as water storage or septic tank capacities.

This comprehensive formula allows for an accurate calculation that is essential for developing on-site sewage facilities. Recognizing the need for capacity calculations in gallons makes it suitable for planning and implementing effective sewage systems.
