2 x 22/7 (Pi) x radius is the circumference.
so 1 cm would be 2 x 22/7 = 44/7 = 6.28 cms.

Circumference of circle is given by the formula:-
C = 2πr where r is the radius.
C = 2π x 1 cm = 2π cm = 2 x 3.14 cm = 6.28 cm

formula for circumference is 2(pi)r where r is radius and pi is 3.14
so your circumference is 6.28cm
