Calculating Angular Displacement

[MrRandom66]

Homework Statement

I'm trying to calculate the angular displacement. A pendulum with length L is released at θ=0.10rad at 0s.

Really not sure how to calculate the angular displacement from this. In a previous question we calculated the values of omega, and phi.

Homework Equations

I thought it could be L x Delta θ, but I'm not sure it's correct

The Attempt at a Solution

0.30 x 0.20 rad
