Is the 8cm the radius? If so then the area of the whole circle is 64 so multiply that by the amount you are interested in (225/360): 64(225/360) = 40.0 square cm.

how did you get 64

I did forget to π there, sorry. I meant 64π so the answer is 40π. I got the 64π because the area of a circle is πr^2 where r is the radius of the circle.

Which side are you considering the base? If it's the side between the 60 and the 90 degree sides then the other sides are 6 and 3√3

it's the side between the 30 and 60
anonymous
  • anonymous
then in that case the other sides are 3/2 and (3√3)/2
