What is Relation between the length of the circular arc and the radian measures of its central angle?

You can think of an arc as a fraction of the circumferance of a circle. Also, a complete circle is 2pi radians, so any central angle is THETA / 2pi of a complete circle. Multiply by the circumferance to get the length of the arc: THETA / 2pi * 2(pi)(r) = THETA * r or the length of the arc is simply the radius times the central angle in radians

What is the relation of the three measures of central tendency to a normal distribution?
Equality.
What is the difference between the measures of central tendency and the measures of dispersion?
difference
Which is most stable in the measures of central tendencies?
It depends on what measures you are comparing between!
Application of relation between arc of length and central angle?
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
How skewness help in determining relation between different measures of central tendency?
Negative skewness means the average (mean) will be less than the median. Positive skewness means the opposite. I'm not sure if any rule holds for the mode.

Which statements accurately describes the measures of central tendency?
"Measures of central tendency are statistical measures." is an accurate statement.
Why is range not a measure of central tendency?
Measures of central tendency are averages. Range , the difference between the maximum and the minimum, is a measure of dispersion or variation.
How do you find an average from the measures of central tendency?
One of the measures of central tendency IS the average, also known as mean. You can't calculate the average from other measures of central tendency.
Why does the distance between the earth and moon change?
It varies, since the moons orbit around earth is not perfectly circular and central.
Why nuclear force is non central?
central forces are one which act centre to centre between two particles and are inversely proportional to the square of the distance between them. nuclear forces violate this relation so they are non central in nature.
What are the benefits of measures of central tendency Explain with an example?

How do you find the measures of a central angle?
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
