9-yes

11-first circle

2 pye r = 132

= 2×22/7 × r = 132

= r = 132 × 1/2× 7/22

= r = 3 cm

Area= pye r square

22/7 × 9

= 198/7

second circle

2 pye r = 88

= 2 × 22/7 × r = 88

= r = 88 × 1/2 ×7/22

= r = 2 cm

Area = pye r square

= 22/7 × 4

= 88/7

Area of the ring = 198/7- 88/7

= 198- 88/7

= 110/7
