Answer:

7.07 cm

Step-by-step explanation:

we know,

circumference = 2πr

so,

2 × 22/7 × r = 66

44r = 66×7 = 462

r = 462/44 = 1.5

therefore, radius of the circle is 1.5 cm.

now,

we know , area = πr²

so,

22/7 × (1.5)²

22/7 × 2.25

49.5/7

7.07 cm (approx)

therefore, area of the circle is 7.07 cm (approx.)

hope this answer helps you!
