## Excel formulas for Circle Segment (or Sector) arc radius and segmented angles

The length of the arc and thickness of the chords are determined by the sum of the TIV. You can see not only which city or policy class recorded the highest and lowest values, but also the policy classes that contribute to the sum of TIV for each city. Miami recorded the largest sum of TIV in each policy class, while cities such as Saint Petersburg and Jacksonville have policies in three out of the four policy classes.

Each chord is bidirectional, with its thickness and value determined by the extent of the relationship or volume of the flow between the categories. A census bureau department is studying the state-to-state migration flows among eight states on the West Coast of the United States in a particular year.

A chord diagram can be used to determine the migration behavior among the states. The arc length for each state represents the flow migration into the state, so you can see which states recorded the highest influx. The chords show the directed flow between states.

In the ratio layout, each chord represents the bidirectional flow between two states, so tapered chords indicate more volume of flow in one direction than the reverse. For example, more people migrated from Alaska to California than vice versa. Pi is equal to 3. What's the Length of the Circumference of a Circle? If the diameter of a circle is D and the radius is R. Angles are measured in degrees, but sometimes to make the mathematics simpler and elegant it's better to use radians which is another way of denoting an angle.

### arc length formula

A radian is the angle subtended by an arc of length equal to the radius of the circle. A right-angled triangle has one angle measuring 90 degrees. The side opposite this angle is known as the hypotenuse and it is the longest side. Sine and cosine are trigonometric functions of an angle and are the ratios of the lengths of the other two sides to the hypotenuse of a right-angled triangle. However sine and cos are derived from the sides of an imaginary right angled triangle superimposed on the lines.

In the second diagram below, you can imagine a right angled triangle superimposed on the purple triangle, from which the opposite and adjacent sides and hypotenuse can be determined.

Over the range 0 to 90 degrees, sine ranges from 0 to 1 and cos ranges from 1 to 0 Remember sine and cosine only depend on the angle, not the size of the triangle. So if the length a changes in the diagram below when the triangle changes in size, the hypotenuse c also changes in size, but the ratio of a to c remains constant.
