What is the distance (in cm) travelled by the tip of the minute hand of a clock (of length 10 cm) in 15 min? (a) 10 p (b) 5 pi (c)pi/10 (d) 20 pi

Answer 1

Answer:

5pi

Step-by-step explanation:

The minute hand moves through 2π×15/60= 2π radians.

Since the length of the minute hand is 10cm, the distance moved by the tip of the hand is given by the formula,1 = rθ = 10×π/2 = 10π/2 =5π cm
