Comparison of Several Calculation Formulas of Circular Arch Area
Abstract
In our daily life and work, we often meet the closed figure of arc and straight line. The measurement and calculation of arcuate area is unavoidable. In this paper, the theoretical formula based on the center angle and radius of the circle, the calculation formula based on the arc length and chord length, the accurate calculation formula and approximate calculation formula based on the arc length and height, three calculation formulas based on the chord length and height, and the approximate calculation formula based on the arc length, chord length and height are given. The calculation formulas are compared for the convenience of practical application.
