A circle with the center O has radius of 1 unit. There is also another circle with diameter AB.
Find the area of the shaded region.

quarter of circle ABO = 0.25*3.14*1*1 = 0.785
triangle ABO = 0.5*1*1 = 0.5
area of sector AB = 0.285
semicircle with diameter AB= ((sqrt(2))/2) ^2 * 3.14 *0.5= 0.785
so that shaded area = 0.785 - 0.285 = 0.5
bener ga?
Bener dong :p
Yg kurang tepat kata2 "area of sector AB", harusnya "area of segment AB"
One commendation ticket to you tomorrow :D
