Question

The minute hand of a clock is 14 cm. How far does the tip of the minute hand move in 1 hour?

• A. 88 cm
• B. 66 cm
• C. 110 cm
• D. 44 cm

Answer 1

The correct option is A 88 cm

To find the distance covered by the tip of the minute hand in one hour, we have to find out the circumference of a circle having its radius = length of the minute hand
So, Circumference = $2\pi r=2\times \frac{22}{7}\times 14=88cm$
Therefore, the minute hand covers a distance of 88 cm in 1 hour.
