basically find the area of the bigger and smaller circle

a = pi * r^2

a = 3.14 * 7^2
a = 3.14 * 49
a = 153.86

a = 3.14 * 11^2
a = 3.14 * 121
a = 379.94

subtract the smaller area from the larger area:

379.94 - 153.86 = 226.08 sq cm

Answer:

Explanation:

Non-shaded region area:

A= 3.14 x 7^2=153.86 cm²

The whole circle area:

A=3.14 x 11^2= 379.94 cm²

Area for ONLY the shaded region:

A= 379.94 - 153.86= 226.08 cm²
