A:### Quick Answer

**The number Pi, symbolized by a Greek letter, has a constant value that approximately equals 3.14159.** Pi is an irrational number, which means it cannot be expressed as a common fraction, and it has an infinite decimal representation without any repeating pattern.

Pi, by definition, is the ratio of a circle’s circumference to its diameter (Pi = C/d). This constant is used to solve the area of a circle, with the formula “Pi r squared” or “the product of Pi and the square of the length of the radius.” The rounded-off version of Pi is accepted for general computations. Here’s Pi up to 20 decimal digits: 3.14159265358979323846.

A:

Full Answer >**The number of radians in a circle is equal to 2 pi, or approximately 6.28.**Since there are 360 degrees in a circle, each radian is equal to 360 divided by 6.28, approximately 57.3 degrees.Filed Under: - Q:
## What is the dot product of parallel vectors?

A:

Full Answer >**The dot product of two parallel vectors is equal to the algebraic multiplication of the magnitudes of both vectors.**If the two vectors are in the same direction, then the dot product is positive. If they are in the opposite direction, then the dot product is negative.Filed Under: - Q:
## What is the arctan square root of 3?

A:When considered in radians, the arctan of the square root of 3 is equal to pi over 3, or 1.047. If the square root of 3 is considered in degrees, the arctan of the square root of 3 is equal to about 59.97.
