In the given figure, O is the centre of the circle whose diameter is 14 cm. Find the perimeter of the figure. (Use \[\pi =\frac{22}{7}\].)

A)  134cm                 

B)         124cm

C)  112cm                                 

D)  160cm

Correct Answer: A

Solution :

 Radius of circle = 14 cm - 2 = 7 cm    One side of the figure opposite to 35 cm = 35 cm - 7 cm = 28 cm           Perimeter of the two sectors of circle\[3\times =219\] \[\text{1}0\text{32 }=\text{ 4}0\text{8 }\times \text{ 2 }+\text{ 216}\]Total perimeter = 134 cm         The perimeter of the given figure is 134 cm.
