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.

## How do you find the area of a right triangle?

A:The formula for the area of any triangle equals 1/2 the base times the height. For a right triangle, this is easy to remember ,since a right triangle is half of a rectangle on one side of its diagonal, and the area of a rectangle equals base times height.

## What is the formula for linear interpolation?

A:

Full Answer >**The value of y in the linear interpolation equation is defined as a sum of y0 and the product of y differential (y1 – y0), multiplied by the ratio between differentials of x ((x – x0) divided by (x – x1)).**This is a method of calculating the unknown value of y for any given x on the interval between two known points with coordinates (x0,y0) and (x1,y1).Filed Under: - Q:

A:

Full Answer >**In math, the term "sum of a geometric series" describes the value when all of the terms in a geometric series are added together.**The sum of the terms in a geometric series can be found using the generic formula a * ([1 - r^n]/[1 - r]).Filed Under: - Q:
## What is a geometric pattern in math?

A:

Full Answer >**A geometric pattern refers to a sequence of numbers created by multiplying a specific value or number by the value of its previous one.**As long as there are more than two numbers in the pattern, multiplication can be used to continue the pattern or find any missing numbers.Filed Under:
