If a circle of maximum area is cut out of the square paper, what is the percentage wastage of the paper in this process? (π = 22 /7)1). 202). 150/73). 160/74). 10 |

Answer» LET the side of the SQUARE be 2x ⇒ Diameter of the circle = Side of the square ⇒ Radius of the circle = x ⇒ Area wasted = Area of the square – Area of the circle= (2x)2 - π x2 ⇒ x2 (4 – 22/7)= 6x2/7 ∴ Percentage WASTAGE = Area wasted/Area of square × 100 = (6x2/7)/4x2 × 100 = 150/7% |
