Question 888420: If a circle has a radius length of 2x units, what is the circle’s circumference?
The choices are:
1) pi(x)
2) 1/2 pi(x)
3) 4 pi(x)
4) 2 pi(x) Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! The formula for circumference of a circle is C=Pi*Diameter (or 2 Pi R)
If the radius is 2x, simply insert that value into the formula to get
C = 2 Pi (2X) or C = 4 Pi X
