A circular clock has a radius of 14 cm. Calculate the distance covered by the tip of the minute hand in 30 minutes, assuming it is positioned at the edge of the clock face. (Use π = 22/7)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 44 cm.
Radius = 14 cm
Circumference of clock = 2πr = 2 × × 14 = 88 cm
In 30 minutes, the minute hand covers half a circle.
Distance covered = = 44 cm
