Heya !!!
Let the radius of the circle be r cm.
Therefore,
2πR = 66
2 × 22/7 × R = 66
R = ( 66 × 7/44)
R = 21/2 cm
Therefore,
Area of the cricle = πR² cm²
=> ( 22/7 × 21/2 × 21/2 ) cm²
=> ( 22 × 21 × 21 ) / ( 7 × 2 × 2) cm²
=> 346.5 cm².

circumference of the circle is = 2πr=66
= 2×22/7×r=66
= r = 66/22 × 2× 3
= r = 18
area of the circle is πr²= 22/7 × 18²
