Solution

The correct option is C
7

$C i r c u m f e r e n c e o f T y r e$

$= 2. π . r (D i s t a n c e t r a v e l l e d i n e a c h r o t a t i o n)$

$T o t a l D i s t a n c e = D i s t a n c e c o v e r e d i n 1 r o t a t i o n \times 300$

$0.132 = 2 \times \frac{22}{7} \times r \times 300$

$r = \frac{0.132 \times 7}{2 \times 22 \times 300}$

$r = 7 c m$

The correct option is C 7 Circumference of Tyre =2.π.r(Distance travelled in each rotation) Total Distance=Distance covered in 1 rotation×300 0.132=2×227×r×300 r=0.132×72×22×300 r=7 cm
