Basically, the circumference of a circle is the perimeter of the circle.
the circumference is the distance around a circle. Can be found by diameter * 3.14(pi).
If you mean circumference of a circle then that is its Latin roots
Circumference= 2(Pi)r so just work backwards :)
How do you get the diameter
LxW
-(-40) = +40.
Divide the circumference by 2pi
circumference=pi x diameter
Divide the cirumference by 3.14
75.37
It could mean Automatic Data Processing, that is, using a computer for working with data.
