Units: Note that units of length are shown for convenience. They do not affect the calculations. Geometry calculator solving for circle arc length given radius and central angle.
On the picture: L - arc length h- height c- chord. If you know radius and angle you may use the following formulas to calculate remaining segment parameters: .
Radius and diameter refer to the original circle , which was bisected through its center.
Enter one value and choose the number of decimal places.
Thales of Miletus, Radius (r):, Semicircle. Solve area, diameter, and circumference, circle equations. The radius can be any measurement of length. This calculates the area as square units of the length used in the radius. Circle Sector calculator , Circle Segment Calculator , Arc Calculator , Circle Chord Calculator.
Click CALCULATE and your answer is 14. Simply enter the desired value in the relevant box. Please use only numbers (e.g. enter not cm). A secondary school revision resource for GCSE Maths about higher level shapes and circles. But you must be careful to use the correct length for the formula ( the radius or diameter).
In this case, the centerpoint of the arc must be created above the width instead of below and the arc is drawn as before. Check out also the Calculator for Radius . Clearly the angle cannot be greater than 3degrees. A problem not dealt with by this calculator . Definition of arc length and formula to calculate it from the radius and central angle of the arc. Regardless what information you are given, you can find out the diameter . Calculations of geometric shapes and solids: the Circle.
The units of length that will not affect the calculations.
