From a square piece of a paper having each side equal to 10 cm, the largest possible circle is being cut out. The ratio of the area of the circle to the area of the original square is nearly :	Choose the correct choice:
A) 4⁄5 B) 3⁄5 C) 5⁄6 D) 6⁄7 E) None of these
4⁄5rea of the square = (10)2 = 100 cm2   4⁄5rea of the circle = 22⁄7 × (5)2 = 22×25/7   Required ratio = 22×25/7×100=22/28=11/14   = 0.785 ≈ 0.8 = 4⁄5   4⁄5nswer 4⁄5
