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.

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.
Full Answer >The height of an equilateral triangle is equal to the square root of three divided by two and multiplied by the length. The equation for the height of an equilateral triangle is based on the Pythagorean Theorem.
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.
