Calculate the area of the sector bounded by DQ, EQ, and arc DE. Picture: http://ce.byu.edu/courses/hs/GEOM-043-101/secure/imgs/math10-1721.gif

OpenStudy (anonymous):

DE is 6pi and circle Q is 225 pi, if I've calculated right.

OpenStudy (anonymous):

lose the triarc, which is 72/360 of the area.

OpenStudy (anonymous):

The area of...?

OpenStudy (anonymous):

360/360 is the circle and the triarc is 72/360

OpenStudy (anonymous):

gotcha... So I have 141.37 as sector area but my options are: a. 6pi b. 10.8pi c.45pi d. 72pi ...?

OpenStudy (anonymous):

72/360 * 225 pi is?

OpenStudy (anonymous):

141.37

AHA! Figured it out. Thanks for the help :)
