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
=>The Radius of Circle is 10.5cm and the area of circle is 3.465cm²
Circumference = 66cm
2πr = 66
r = 66 × 7 /44
r = 21/2
r = 10.5 cm
For area :-
πr²
= 22/7 × ( 10.5 )²

Answer:
Step-by-step explanation:
Circumference of a circle= 2πr
66=2πr
33=πr
R=11.5
Area of the circle = πr^2
=22/7×11.5^2
=415.64
Actually I've did something wrong here . So don't consider this to be an answer. A small calculation mistake
okey
