A bicycle has a radius of 30 what? Once you have the units for the radius, multiply the radius by 
. Using 3.14 for 
should be plenty close enough, although 
is a very precise (6 decimal place) rational approximation. Once you have done the arithmetic with the units given for the radius, convert to millimeters. THEN, and only then, round off.
