Question

The minute hand of a clock is 20cm long. Calculate displacement of its tip between 6 am and 6:15 am​

Answer 1

31.43cm

Explanation:

premeter of circle = pie × diameter

r= 20cm => D = 2×20 = 40cm

P = 22/7 ×40 = 125.71 cm

Displacement from 6 am to 6,15am = 1/4 ×P

= 125.71/4 = 31.43cm
