○ 6.2831
○ 157.07
○ 314.1592
○ 376.9911
3 of 10 questions remaining

Explanation:

Step1: Recall the formula for angular frequency

The formula relating angular frequency ($\omega$) and frequency ($f$) is $\omega = 2\pi f$.

Step2: Substitute the given frequency

Given $f = 50$ Hz, substitute into the formula: $\omega = 2\times\pi\times50$.

Step3: Calculate the value

Using $\pi\approx3.141592$, we have $\omega = 100\times3.141592 = 314.1592$.

Answer:

314.1592 (which corresponds to the option "314.1592")
