Pi is not a size. Pi is usually 22/7. Sometimes also 3,14. Pi is used to measure area and circumference of a circle, and the volume of sphere / tube. If there is no pi, then the area and circumference of circle, and the volume of sphere / tube will not be counted.
1 rad = 180°/pi Example: 1.6 rad = 1.6(180°/pi) 1.6 rad = 2880°/pi
circumference = 2*pi*radius or diameter*pi
Pi is a series of unending decimals after a 3. The first one hundred digits of pi are: 3.14159265358979323846264338327590288419716939937510582097494459230781 64062862989986280348253421170679

Degrees = (180/pi)*Radians
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.

circumference = 2*pi*radius or diameter*pi
It is 420/180*pi radians = 2.33... *pi radians or 7.3304 radians (approx).

measure radius, and cube it. multiply the cubed radius by pi. multiply that answer by 4/3. done
Degrees = (180/pi)*Radians
No. Pi was discovered by mathematicians to measure the circle.
measure the circumference, c. Since c = pi x d where d = diameter pi = 3.1415926535897932384676..... diameter = circumference / pi
circumference of a circle = 2*pi*radius or pi*diameter area of a circle = pi*radius squared
