Shell program to calculate the area and circumference of the circle given the radius A sector is created by the central angle formed with two radii, and it includes the area inside the circle from that center point to the circle itself. The portion of the circle's circumference bounded by the radii, the arc, is part of the sector. Arcs of a Circle. Acute central angles will always produce minor arcs and small sectors How to use irregular area calculator? Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other). Step 2: Enter length of horizontal sides into Length 1 and Length 2. And Width of the vertical sides into Width 1 and Width 2. (See image above). Step 3: Press calculate button. The output our calculator provides is independent of the unit of measurement
