formula for the area of a circle sector of B degrees is: A=1/2B*2Pi*(B/360)r^2

OpenStudy (anonymous):

what side would I chose as the radius?

OpenStudy (anonymous):

say for the sector with the vertex angel 60 degrees

OpenStudy (phi):

The sector with a central angle of 60 degrees has the shortest radius. OA= 2 must be the radius. Area (of this sector) should be 60/360 or 1/6 of a full circle's area.
