this is kinda hard to explain...?

I'm assuming that A and B are on the circle and O is the center of the circle.  Since OB=6, AB=6 as well, since OB and AB are radii.\n\n1.  Area of a circle = pi*r^2\n= pi*(6)^2\n= 36pi\n\n2.  Area of a sector (pie wedge) is easiest if you consider that the pie wedge is a certain fraction of the whole circle.  In this case, your sector is 60 degrees, and the whole circle is 360 degrees.  So the sector is 1/6 of the total area, which we found in part 1.  So the area = 6pi.\n\n3.  The segment is trickier.  If you look at the triangle, the segment is the curved part - almost like the top of the ice cream cone, if you can follow my description.\n\nThe area of a segment is given by\n\nA = r^2[theta - sin(theta)]/2\n\nwhere theta is the angle in radians.  The angle we have is 60 degrees.  To convert to radians, multiply by pi/180.  So theta is pi/3.\n\nNow since we know that the triangle has a 60 degree angle, and that OA and OB are both 6, through some reasoning we can see that this is an equilateral triangle, and AB (the chord) is also 6.\n\nSo the area of the segment then is\n\nA = r^2[theta - sin(theta)]/2\n= (6)^2[pi/3 - sin(pi/3)]/2\n= 3.26\n\n4.  Circumference = 2*pi*r\n= 2*pi*6\n= 12pi\n\nI don't think that X served any purpose except to indicate the region you're supposed to be considering for this problem.
