See this problem
I answered this as \frac{120}{360} (10)^2 \pi since the question asks for the segment PRQ which is wrong.
Does the question expect us to subtract out the Triangle? If so, how would you refer to the entire segment including the Triangle?
To refer to the entire segment, you would have OPQ
PRQ is a segment.
A circular segment or disk segment is a region of a disk which is “cut off” from the rest of the disk by a straight line
OPRQ, the entire thing whose area you are calculating is a circular sector.
A sector is said to be a part of a circle made of the arc of the circle along with its two radii. It is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc.
I’m not a 100% of the accurate mathematical notation. In real life, I’d be using the sector ⌔ symbol and the segment symbol ⌓ to clarify along with the correct word.
