A wire of length 88 cm is first bent into a square and then into a circle. Taking π = 22/7, by how much does the area of the circle exceed the area of the square?
Correct answer B. 132 sq cm
Explanation
Square side = 88/4 = 22 cm, area 484 sq cm. Circle: 2πr = 88, r = 14 cm, area = 616 sq cm. Difference = 616 - 484 = 132 sq cm.
