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 =
