Good question from Circles: Q) I had a circular compact disk with a perimeter of length 44 cm. I broke it into two pieces along a chord of length 7 cm. What is the ratio of the perimeter of the larger part to the smaller part? (a) 131 : 43 (b) 5 : 1 (c) 22 : 3 (d) None of these  |

hi jayesh, ans will be a)131:43 since here we get equilateral triang;e as radius is also 7 here so it will subtend 60 dgrree at the centre thereby smaller perimeter will be (44/6)+7 and larger will be( 44-44/6)+7 so ratio of larger to smaller gives 131:43 |
