Hi friend
---------------
Your answer
--------------------

Circumference of a circle given = 66 cm

Then,
---------

2 × π × r = 66

=> 2 × 22/7 × r = 66

=> r = (66× 7)/(22 × 2)

=> r = 10.5 cm

Therefore,
------------------

Diameter = 2 × Radius

=> (2 × 10.5) cm

=> 21 cm

HOPE IT HELPS

circumference = 66
circumference of circle = 2πr
for diameter
2πr=66
2*22/7*r= 66
by cross multiply
66*7 =2*22*r
