Okay thanks

what fraction of the circle is made up of 120°?

zarkam21 (zarkam21):

120/360righht

OpenStudy (mrnood):

yes that is 1/3 so the shaded area is 1/3 of the total area of the circle the circle has radius 8 - so what is its area?

zarkam21 (zarkam21):

201.06

OpenStudy (mrnood):

OK That is the area of the whole circle so what is the area of 1/3 of the circle?

OpenStudy (mrnood):

You are just one simple step from the answer the diagram shows that the shaded area ia 1/3 of the total area you have worked out the total = 201.06 so what is 1/3 of that?

zarkam21 (zarkam21):

67.02
