A wire in the shape of a circle of radius 14 cm is bent in the form of a square, what is the difference of their areas?
Answer & explanation
Correct answer: option 1
Circumference of wire = Perimeter of square
2\(\pi\) x 14 = 4 x (side)
88 = 4 x (side)
Side = 22
Difference in their areas = \(\pi\)r² - (Side)² = 616 - 484 = 132 cm²
