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 :)

circumference of circle=2πr
2×22/7×r=66
r=66×7/2×22
r= 462/44
r=10.5 m
we know r=2d
10.5×2
r=21 m answer hope this will helps u please mark as a brainlist answer
