What is the ratio of the circumferece of a circle to its diameter called?
circumference:diameter = pi (about 3.14...)
What is the circumferece if the radius is 56?
Well, we know that if a circle has a diameter of 1, the circumference is pi, and we also know that the radius is 1/2 of the diameter, so we multiply the radius (56) by 2 to get 112, which we multiply by pi to get the circumference. So, we could either assume pi is 3.1415926, or we could express this number as 112π units, or as 351.858371 units.
Does mean mean average?
No, but sometimes "average" means "mean" - when it doesn't mean median, geometric mean, or something else entirely.
What is radian?
"Radian" is an angle, of a very specific size. If you draw a 1-radian angle from themiddle of a circle, then the length of the piece of the circle that it cuts out is exactlyequal to the length of the circle's radius.Since the length of the circle's full circumferece has 2pi times the radius in it, the full360 degrees of angle in the circle has 2pi radians in it.That makes the size of each radian 360/2pi = about 57.3 degrees (an irrational number).Just reading about it now, you don't see any reason to use an angle with sucha complicated definition, especially if you can never exactly write the number ofdegrees in it. But when you get into Physics, Calculus, Electricity, Engineering,and Trig, this angle starts to pop up everywhere.
