Answer:
Area of the bigger circle= πr².
radius=14/2=7cm.
area = 22/7×7×7.
Area=154cm².
Area of the shorter circle= πr².
radius =7/2=3.5cm.
area=22/7× 3.5×3.5=38.5 cm².
area of the shaded region= area of the bigger circle - shorter circle
area = 154cm² - 38.5 cm²
area =115.5 cm² is the area of the shaded region.
