It is missing any sign you've actually tried to solve the problem...
Surely a web search could teach you the concepts needed to answer the question. Asking for help is where you seek clarification. This appears to be more of a "hey can you do this for me?" sort of question. Those aren't cool.

Exactly what is unclear? You're given an angle theta, corresponding to one sector of the circle, and a formula for finding the area using theta, as well as the total radians in a circle (hint: total minus theta gives you a new "theta" corresponding to PQN). Why not plug and chug and see where that gets you?

If you had read my OP I think the question is worded wrong and need
clarification if this is the case
It's worded correctly.
Point O is at the center of the circle.
Angles POQ and NOQ split the circle into "sectors".
You know the angle of NOP; finding the other angles is trivial.
You know how to find the radius of the circle; you can find the radius from lines ON or OP.
If you know how to use sin and cos, you can find the width and height of the triangle, and from there, find its area.
