The pi value never ends because it is an irrational number. The 100th digit after the decimal point is 9. Since pi is an irrational number, the digits after the decimal point are infinite. The value of pi starts with a 3 followed by a decimal point. What are the First 100 Digits of Pi Value? The value of pi is extensively used in the concepts of measurement of surface area, the volume of 3D shapes, etc. It is an irrational number which means that the decimal places after 3 are never-ending. The pi symbol is mostly used to calculate the circumference of circles, surface area, and volume of three-dimensional shapes. The pi symbol is denoted as 'π' which is a Greek alphabet. Sometimes, to ease the calculation, the value of pi is used in the form of a fraction as 22/7. It is denoted by the Greek letter 'π' and is spelled as 'pie'. It is an irrational number often approximated to 3.14159. Pi, in mathematics, is a constant which is the ratio of the circumference of a circle to its diameter.

So, for half a circle, the arc length is πr and the radius is r. The formula of radians is arc length/radius. And, for half a circle, the angle is 180° and the length of the arc will be 2πr/2 = πr. So, we can write, Circumference = 2πr = 360 degrees.
It means if we rotate by 360° around a point (known as the center of the circle) at a fixed distance (radius), we will get the circumference, which is equal to 2πr, where r denoted the radius of the circle. We know that in a circle, one complete revolution makes the circumference of the circle. To understand this, we will be looking at the concept of radians which is the SI unit of measuring angles. The value of pi in degree is 180 degrees, as π radians is equal to 180°.
