Question

A scotter wheel makes 50 revolution to cover a distance of 88m then the radious of wheel?

Answer 1

Let the radius of the wheel be r

then the distance that the wheel will cover by one revolution = $2\pi r$
                                                                                                = $2 \times \pi \times 88 = 2 \times \frac{22}{7} \times 88 = \frac{352}{7} m$
