the formula for circumfirence is self descriptive C=2 r pi the 2pi part refers to 360 degrees which is a full circular arc multiplied by the radius, as the reduis gets larger so does C.
given C=57= 2pi r
r= 57/2pi
now if the 9 is in degrees then C=9/360 (2pi r)=1/40 (57)
if 9 is radians then :
C= (9/2pi) 2pi r = 9r
C= 9 (57/2pi)
