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.
Know MorePi, 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.
Learn more about GeometryThe 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.
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.
Full Answer >The equation for height, width and length would equal the volume of a cube or a rectangular solid. Length times width equals area, then multiplying area by height equals volume.
Full Answer >If calculating the secant when using pi in radians, the ratio known as secant of pi, or sec pi, is equal to -1. The secant of pi is equivalent to 1/(cos pi).
