Question

a minute hand of a clock is 1m long. the distance covered by the tip of the minute hand from 3:00to 3:30 is

Answer 1

$1 \times \frac{591}{? \\ 2.52}$

Answer 2

Concept

As we can see in the question a minute hand is travelling from 3:00 to 3:30 means if we draw its figure is will form  1/4 part of a circle in which the length of the minute hand indicated the circle.

So , we know that Distance is product of radius and the arc

Distance =  πr

              =  22/7 × 1

Distance = 3.14 km
