Problem

Suppose that point $P$ is on a circle with radius $r$, and ray $O P$ is rotating with angular speed $\omega$. Complete parts (a) through (c). \[ r=8 \mathrm{~cm}, \omega=\frac{\pi}{12} \text { radian per } \mathrm{sec}, \mathrm{t}=8 \mathrm{sec} \] (a) What is the angle generated by $P$ in time t? \[ \theta=\square \text { radian } \] (Type an exact answer, using $\pi$. Use integers or fractions for any numbers in the expression.)

Solution

Step 1 :Given that the angular speed \(\omega = \frac{\pi}{12}\) radian per sec and time \(t = 8\) sec.

Step 2 :The angle generated by a point on a circle with radius \(r\) and angular speed \(\omega\) in time \(t\) is given by the formula \(\theta = \omega \cdot t\).

Step 3 :Substitute the given values into the formula to find the angle \(\theta\).

Step 4 :So, \(\theta = \frac{\pi}{12} \cdot 8 = \frac{2\pi}{3}\) radians.

Step 5 :Final Answer: The angle generated by \(P\) in time \(t\) is \(\boxed{\frac{2\pi}{3}}\) radians.
