yes pi is a measurement

circumference = 10.8*3.14 = 33.912 units of measurement.
To express a quantity in terms of pi, you need to relate it to a circular measurement, such as the circumference or area of a circle. For example, if you have the circumference of a circle, you can use the formula ( C = 2\pi r ), where ( r ) is the radius, to express the circumference as a multiple of pi. Similarly, for the area, use ( A = \pi r^2 ) to express the area in terms of pi. Simply factor out pi from the equation to achieve the desired expression.
PI isn't an abbreviation it's a number, it's a measurement around a circle.
It is pi/2 + 2*k*pi radians for integer k.
circumference of a circle = 2*pi*radius or pi*diameter
circumference = 2*pi*9.5 = 19*pi units of measurement
Circumference is the perimeter or the measurement of outline of a circle and pi is represented as 22 divided by 7.
It is: 6*pi units of measurement
It is: 6*pi units of measurement
Pi is used in nearly every branch of math. If you need to do anything with a circle, pi was used to make that circle. Any measurement of a circle, cylinder, sphere, etc involves pi. Pi is incorporated into the GPS. All kinds of things use pi. A fun fact for pi: the actual length of a river compared to the straight distance from source to mouth will yield pi.
