A related formula can be used to derive the radius of an arc from span and displacement measurements. See How the arc radius formula is derived. Discuss the formula for arc length and use it in a couple of examples. degree. **Albina takes no responsibility for the calculated results. In case you're new to circles, calculating the length and area of sectors could be a little advanced, and you need to start with simpler tools, such as circle length and circumference and area of a circle calculators. Thus, the length of an arc is equal to the radius r of the sector times the . =. Step #2: Enter the value of Radius. You will also learn the equation for sector area. (For more about the math behind these calculations, see Math Behind the Arc Radius and Length sidebar.) The length of the chord, sagitta and radius of the arc are inter-related, and if you know any two you can calculate the third. Radius of Circle given Arc Length Solution. For example, enter the width and height, then press Calculate to get the Average acceleration is the object's change in speed for a specific given time period. It works for arcs that are up to a semicircle, so the height you enter must be less than half the width. Plugging our radius of 3 into the formula, we get C = 6 meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. The length of the arc and the angle subtended Radius of Circle given Arc Length calculator uses Radius of Circle = Arc Length of Circle/Central Angle of Circle to calculate the Radius of Circle, Radius of Circle given Arc Length formula is defined as the length of any line from the center to any point on the Circle and calculated using the arc length of the Circle at a particular central angle.
