Answer:

116 cm²

Step-by-step explanation:

Shaded Area = area of the larger circle - area of the smaller circle

Area of the larger circle = πr²

Where,

r = 6.5 cm

Area = π*6.5² = 42.25π cm²

Area of smaller circle = πr²

Where,

r = 2.3 cm

Area = π*2.3² = 5.29π cm²

✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264

Area = 116 cm² (3 S.F)
