The radius and circumference of a circle are related as C=2*pi*R (* stands for multiplication) where C is the circumference(=12 inches in the given case), R is the radius(to be found out) and 'pi' is a constant whose value is approximately 3.141592654. To find R the formula becomes R=C/(2*pi). Substituting 12 inches for C and the value of 'pi' we arrive at the following result:
R or radius=12/(2*3.141592654)=1.909859317 inches.
