Question

A brevela wheel makes 7000 rewolutions in/moving 22 km then the
diametem of the wheel is
av,5m
b)lm
c)0.5 m
d)3 m​

Answer 1

Answer:

Distance covered in 1 revolution = 2 × pi × r

Distance covered in 7000 revolution = 2 × pi × r × 7000

According to statement

$2 × \pi × r × 7000 = 22000 \\ 2r \times \frac{22}{7} \times 7000 = 22000 \\ 2r = 1$

So diameter is 1 m.

Answer 2

Answer:

1m is correct answer.............
