Question

A minute hand of a table clock is 3cm long . how far does its tip move in 20 minute?.​

Answer 1

Answer:

44/7 cm

Step-by-step explanation:

Circumference = 2πr = 2*22/7 * r = 44r/7 cm.

Time travelled in 20 min = 1/3 of the value of Circumference.

C/3 = (44r/7)/3 cm

      = 44/7 cm.

(where 3 cm is the radius).

Therefore, the correct answer is 44/7.
