Circumference of larger circle = 2πr 132 = 2 × 22/7 × r r = (132 × 7)/(22 × 2) = 21 cm. Area of a larger circle = πr² = 22/7 × 21 × 21 = 1386 cm. Circumference of smaller circle = 2πr 88 = 2 × 22/7 × r r = (88 × 7)/(22 ×2) = 14 cm. Area of a smaller circle = πr² = 22/7 × 14 × 14 = 616 cm. ∴ Required difference = 1386 – 616 = 770 cm.
