geo

Answer 3

the 24 one is very simple
just notice, the radius is 8 for the circle, so.. find the area for the whole circle, then
notice, you're asked only for 1 quadrant, the 1st quadrant, meaning, whatever area you get, divide that by 4, and that's the area of that "sector of the circle"

then, find the area of that triangle, simple enough, radius is 8, thus
base is 8
height is 8 also for that triangle

then subtract the triangle's area from the circle's sector
and that'd be the shaded area

because, once you subtract or "remove" the triangle from the Sector, all that's left, is the area that is NOT the triangle, the Segment

wait i need to do 23 and 25
