Given :-
Circumference = 66cm
2πr = 66
r = 66 × 7 /44
r = 21/2
r = 10.5 cm
For area :-
πr²
= 22/7 × ( 10.5 )²
= 3.465 cm²
Circumference = 66cm
2πr = 66
r = 66 × 7 /44
r = 21/2
r = 10.5 cm
For area :-
πr²
= 22/7 × ( 10.5 )²
= 3.465 cm²

We are Given, Circumference of Circle= 66cm
Let radius of circle= r
Then, 2*pi*r=66
2*22/7*r=66
so r= 66*7/22*2=21/2
r=10.5 cm
∴Area of Circle= pi*r*r
= 22/7*(10.5)^2
=22/7*11025/100
=346.5 cm^2
