Answer:

346.5

Step-by-step explanation:

circumference = 2πr = 66

2*22/7*r=66

r= 66*7/2*22

r = 21/2

area=  πr^2 = 22/7*21/2*21*2

= 33*21/2

=693/2

Circumference= 2πr = 66

=> 2×22/7×r= 66

=>. 44/7×r = 66

=>. r = 66×7/44

=>. r = 21/2 cm


Area = πr^2

= 22/7 × 21/2 × 21/2

= 11× 3 × 21/2

= 346.5 cm^2
