Answer
$\theta=20.51$ radians
Work Step by Step
Step 1: The formula to be used here is $w=\frac{\theta}{t}$.
Step 2: After substituting the values of $w$ and $t$ provided by the question into this formula, the equation becomes $4.316=\frac{\theta}{4.752}$
Step 3: Solving, $4.316\times4.752=\frac{\theta}{4.752}\times4.752$
Step 4: Therefore, $\theta=20.51$ radians
