Hello users ....
Solution:-
we know that:
circumference of circle = 2πr or πd
Where, r is the radius and d is the diameter of circle.
now,
According to given :
circumference of circle = 66 m
=> 2πr = πd = 66
=> 22/7 × d = 66
=> 22 d = 66×7
=> d = 66×7 / 22
=> d = 3×7
=> diameter (d)= 21 m Answer
Hope it helps :)

We know that 2πr
Circumference of circle= 66cm
2πr = 66
2*22/7*r = 66
r = 66*1/2*7/22=10.5cm
diameter= 10.5*2=21cm
Circumference of circle= 66cm
2πr = 66
2*22/7*r = 66
r = 66*1/2*7/22=10.5cm
diameter= 10.5*2=21cm
