What will be the area of the largest square that can be cut out of a circle of radius 10 cm?(a) 100 cm2 (b) 200 cm2 (c) 300 cm2 (d) 400 cm2 |

Answer» (b) 200 cm2 From the question it is given that, radius of circle 10 cm. Square has diagonal equal to its diameter. Diameter = 2 × radius = 2 × 10 = 20 cm Then, let us assume the side of the square be P. So, area of square be P2. By the rule of Pythagoras theorem, Diagonal2 = height2 + base2 202 = P2 + P2 202 = 2P2 400 = 2P2 P2 = 400/2 P2 = 200 cm2 Therefore, area the largest square that can be cut out of a circle of radius 10 cm is 200 cm2. |
