1.	13.There are two wires of length 44 cm each. One wire is turned to give theform of a circle and the other is turned in the form of a square. Find thedifference in the areas of two figures so formed.(1) 110 cm2(3) 66 cm2(2) 33 cm2(4) 44 cm2
Answer» Wire 1 = 44 cm diameter Therefore radius = d/2 =44/2 = 22cm Area = π r^2 = 1,521.147 cm^2 Wire 2 = 44 cm Length Therefore Area of sq. = L times L = 44 times 44 = 1,936 sq. cm Difference = 414.85sq. cm

Answer»

Wire 1 = 44 cm diameter

Therefore radius = d/2 =44/2 = 22cm

Area = π r^2 = 1,521.147 cm^2

Wire 2 = 44 cm Length

Therefore Area of sq. = L times L = 44 times 44 = 1,936 sq. cm

Difference = 414.85sq. cm
