The large hand of a big clock is 70 cm long.How many cms. does it's extremely move in 6 minutes time.

We know that, the angle traced by the large minute hand in 60 minutes = 360º

Therefore, angle traced by it in 6 minutes =  

Now, θ = and radius(r) = 70 cm.

Consider l be the arc length moved by the tip of minute hand.

l = rθ =
