Question
The total area of a circle and a square is 5450
cm2; the diameter of the circle is 70 cm, what is the difference between the circumference of the circle and perimeter of the square?Solution
r = 35 cm, side of the square = a cm As per the question, 22/7 × r2 + a2 = 5450 22/7 × (35)2 + a2 = 5450 3850 + a2 = 5450 a2 = 1600 a = 40cm Required Difference = 2 × 22/7 × 35 - 4 × 40 = 220 – 160 = 60cm
