Step-by-step explanation:
Circumference of a circle is 2πr.
so, 2πr = 66
= r = 33/π
= r = 33×7/22
hence , diameter = 21/2 × 2
= 21cm.

Answer:
The Diameter of the circle = 21m
Step-by-step explanation:
The formula to find the circumference of any circle:
Circumference of circle = 2πr or πd
Here, r is the radius and d is the diameter of circle.
The information given to us:
Circumference of the circle = 66 m
Now solving:
=> 2πr = πd = 66
=> 22/7 × d = 66
=> 22 d = 66×7
=> d = 66×7 / 22
=> d = 3×7 = 21
Therefore,the Diameter of the circle = 21m
