Answer:
4π cm
Explanation:
A minute hand travels a full revolution along a circular path in 60 minutes
The distance from the center to the tip of the minute hand = 8 cm
We can consider the movement of the minute hand as being on the circumference of a circle with radius = 8 cm
Circumference = 2π · r
= 2π · 8
= 16π
I5 minutes = 15/60 = 1/4th
So in 15 minutes the minute hand will cover only 1/4th of the full circle
Therefore distance traveled by tip of minute hand
= 1/4 x 16π = 4π cm
