Step-by-step explanation:
a= 7
b=14
Area of larger Circle = 22/7 x 14 x 14
= 22 x 28
= 616
Area of Smaller Circle = 22/7 x 7 x 7
= 22 x 7
= 154
i ) Area of Ring = Area of Larger circle - Area of Smaller Circle
= 616 - 154
= 462 Sq. cm.
Perimeter of Larger Circle = 22/7 x 2 x 14
= 44 x 2
= 88
Perimeter of Smaller Circle = 22/7 x 2 x 7
= 22 x 2
= 44
ii) Perimeter of Ring = Perimeter of Larger circle + Perimeter of Smaller circle
= 88 + 44
= 132 Cm.
