perimeter of shahded part = total perimeter - perimeter of smaller circle
perimeter of bigger circle = 2πr
= 2×22/7×7
= 44 cm
perimeter of smaller circle = 2πr
= 2× 22/7×7/2
= 22 cm
perimeter of shahded part = total perimeter - perimeter of smaller circle
= 44 cm - 22cm
= 22 cm
hence, perimeter of shahded region is 22 cm
hope it's help u......
