Answer:
first find the area of the sector with greater radius and then the area of smaller sector and subtract them
Step-by-step explanation:
area of sector with radius 5cm
=60/360 X 22/7 X 5
=1/6 X 110/7
=1/3 X 55/7
=55/21 cm²
area of sector with radius 4cm
=60/360 X 22/7 X 4
=1/6 X 22/7 X 4
=1/3 X 11/7 X 4
= 44/21 cm²
area of shaded region=55/21cm² - 44/21cm²
=11/21cm²
