Question

If the length of the seconds hand of a clock is 7 cm, then find the distance covered by its tip in 1 minute.

• A. 14 cm
• B. 44 cm
• C. 84 cm
• D. 50 cm

Answer 1

The correct option is B 44 cm

Given:
Length of the seconds hand = 7 cm

In 1 minute, the seconds hand makes one complete revolution. So, the distance covered by its tip will be equal to the circumference of the circle whose radius is 7 cm.

$\therefore \text{Distance covered}=2\times \pi \times Radius=2\times \frac{22}{7}\times 7=44cm$

Hence, the tip of the seconds hand covers 44 cm.
