Which formula is used to find the circumference of a circle when radius is given? (1 point)
C = r
C = 2r
C = 2d
C = r^2
3 answers
C = 2πr
There is no PI choose from one of these:
C = r
C = 2r
C = 2d
C = r^2
C = r
C = 2r
C = 2d
C = r^2
The correct formula to find the circumference of a circle when the radius is given is:
C = 2πr
So, the formula from the options provided would be C = 2r.
C = 2πr
So, the formula from the options provided would be C = 2r.
