HELP FIND THE AREA OF THE SHADED REGION https://media.glynlyon.com/g_geo_2012/8/group103bb.gif

OpenStudy (anonymous):

do you know how to calculate the area of the shaded region?

OpenStudy (anonymous):

no, that's always been my weakest point at geometry. it just doesn't sink into my head

OpenStudy (anonymous):

ok hang on let me get the formula and we will work it out

OpenStudy (anonymous):

thank you!

OpenStudy (anonymous):

Area of shaded region = (A/360)(π r²)

OpenStudy (anonymous):

(60/360)(3.14*6^2) this is your equation

OpenStudy (anonymous):

my answer choices are : \[6\pi - 9 \sqrt{3}\] \[12 \pi - 9\sqrt{3}\] \[9 \pi - 9\sqrt{3}\]

OpenStudy (anonymous):

ok do you know how to convert a whole number to a radical?

OpenStudy (anonymous):

I moved schools just before they taught that, and arrived at the other school after they learned it. so... no :( Geometry isn't my strong suit...

OpenStudy (anonymous):

ok hang then(: dont worry i will help(:

OpenStudy (anonymous):

thanks so much!!(:

OpenStudy (anonymous):

np(: fan me to make it easier in the future

OpenStudy (anonymous):

sureeee

OpenStudy (anonymous):

ok your answer is gonna be the first one if you solve you get 18.84 and that equals out to \[6\pi-9\]

OpenStudy (anonymous):

\[6\pi-9\sqrt{3}\]

OpenStudy (anonymous):

thank you so much!

no problem and can you gimme a medal?(:
