find the area of the shaded sector 12cm and 24°
Well, isn't that just a happy little problem to solve! If you have 25 squares in total and 10 of them are shaded, you can find the percentage by dividing the number of shaded squares by the total number of squares, then multiplying by 100. So, 10 divided by 25 equals 0.4, and when you multiply that by 100, you get 40%. Just like that, you've turned a blank canvas into a beautiful calculation!
I'm really having trouble seeing the shaded region from here, so I can't even beginto find an answer to the question.Here's a tip that could be helpful for you:When you're working on a question that has information along with it ... like adrawing, a photo, or a list of words or phrases ... and the question says thingslike "the following" or "which of these", it always helps to look at the drawing,or read the list. Very often, there's no possible way to answer the question ifyou don't, and that's a big part of the reason that they print those things, eitheralongside the question or under it.
