here is the full question A mirror frame in the shape of an oval is shown below. The ends of the frame form semicircles: An oval is formed by a rectangle with semicircles at each end. The length of the rectangle is 54 inches. The width of the rectangle is 27 inches. Which of the following is the perimeter of the inner edge of the frame? (π = 3.14) 192.78 inches 246.78 inches 277.56 inches 331.56 inches
thank you for coming to help me (:
|dw:1439561471196:dw| this is a crappy picture, but is it close to the picture you have? hard to tell from the words
its sad that they give pi away like that :(
ikr a picture would be really helpful here
wait im gonna show you a picture 1sec
i cant see it bud
ok break it up into multiple shapes
what do you see?
the length of each of half-circle, is: pi*radius=pi* diameter/2= 3.14 *27 /2 =... please complete
I'm sorry, I can not give the direct answer, since it is against the Code of Conduct
what is: 3.14 *27 /2 =...?
correct! Now we have two of such half circle, so the total length is: 2*42.39=...?
what is: 2*42.39=...?
correct, now you have to add the measures of the two straight sides, so we have to compute this: 84.78+(2*54)=...?
