The first equation for the tangent to a circle: To use this online calculator for chord length of circle, enter radius of circle (r) & central angle of circle (∠central) and hit the calculate button. Central angle is the angle that is formed by circle at the center by the 2 given points.
The Complete Circular Arc Calculator.
The arc of a circle calculator developed by icalculator requires you to enter the radius or the diameter (whichever is available) and the angle in degrees. If the diameter is given instead, first divide it by two, then repeat the above. While a circle, symbolically, represents many different things to many different groups of.

The formula for the exterior angle is given by. Solves all twenty one cases when given any two inputs. In above figure the curved shape ‘aboa’ is a quarter circle of radius r.
A Quarter Circle Is A One Fourth Part Of A Full Circle.
Examples of the perimeter of a circle calculation from the radius or diameter. A circle is divided into a number of sectors (pie slices). Given any one variable a, c, r or d of a circle you can calculate the other three.
Use This Circle Calculator To Find The Area, Circumference, Radius Or Diameter Of A Circle.
The formula for the area of a sector is (angle / 360) x π x radius 2. There is an alternative arc length formula that defines how to find it if the sector area and central angle are identified. A = r² * θ / 2 = 15² * π/4 / 2 = 88.36 cm².
