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

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.


What is the relation between SHM and uniform circular motion?

Simple Harmonic Motion (SHM) involves an oscillating motion back and forth around a central equilibrium point, while uniform circular motion involves an object moving in a circular path at a constant speed. The two are related in that the projection of uniform circular motion onto one axis can produce SHM, such as the motion of a pendulum. Mathematically, SHM can be described using trigonometric functions that are similar to those used to describe uniform circular motion.


Which statements accurately describes the measures of central tendency?

"Measures of central tendency are statistical measures." is an accurate statement.


What is the formula for calculating the circular orbit velocity of an object around a central body?

The formula for calculating the circular orbit velocity of an object around a central body is v (GM/r), where v is the velocity, G is the gravitational constant, M is the mass of the central body, and r is the distance between the object and the central body.


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.


What is the formula for the velocity of an object in circular orbit around a central body, where vsqrt(gm/r)?

The formula for the velocity of an object in circular orbit around a central body is v (gm/r), where v is the velocity, g is the gravitational constant, m is the mass of the central body, and r is the distance between the object and the center of the central body.
