circumference = 10.8*3.14 = 33.912 units of measurement.
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.

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.
pi*radius2 = 225*pi Divide both sides by pi and then square root both sides: radius = 15 units of measurement
