Calculate the area, the length of arc, and the length of chord of segment from the radius and the central angle using the formula.

When radius r and central angle θ is input and "Calculate area of segment" button is clicked, the area, the length of arc, and the length of chord of the segment are calculated and displayed.

### Area of segment of the radius is 1, and a central angle is 60°

Area r: 0.09058607370608Circular arc length L: 1.0471975511966

Length of chord a: 1
