Properties of a Quarter-Circular Area
This tool calculates the basic geometric properties of a quarter-circular area. Enter the shape dimensions R or D below. The calculated results will have the same units as your input. Please use consistent units for any input.
Arc length =
The area A, the perimeter P and the arc length L of a quarter-circular area, with radius R, can be found with these formulas:
The centroid (center of gravity) of the quarter-circular area is located at equal distances from the radial edges that define its border, given by the formula:
