Answer:
So minute hand will rotate [tex]\pi radian[/tex] in half an hour
Step-by-step explanation:
In one hour minute hand of clock rotate about 360°
So in half an hour minute hand clock rotate [tex]\frac{360}{2}=180^{\circ}[/tex]
We have to find how many minute hand rotate in radian
For conversion of degree to radian we have to multiply with [tex]\frac{\pi }{180}[/tex]
So [tex]180^{\circ}=180\times \frac{\pi}{180 }=\pi radian[/tex]
So minute hand will rotate [tex]\pi radian[/tex] in half an hour
