Answer:
Therefore the tip of the minute hand on the clock moves 56.57 cm in 45 minutes.
Step-by-step explanation:
Using this formula to find the length of the arc
Arc length = [tex]2\pi r (\frac{\theta}{360} )[/tex]
Here [tex]\theta = \frac{360}{60}\times 45[/tex] [for 45 minutes]
[tex]=270^\circ[/tex]
Radius(r) = length of the minute hand = 12 cm
The length of the arc is = [tex]2\pi \times 12\times \frac{270}{360}[/tex]
= 56.57 cm
Therefore the tip of the minute hand on the clock moves 56.57 cm in 45 minutes.
