find the area of the shaded sector 12cm and 24°
10 / 25 = 4 *10 / 4 * 25 = 40 / 100 = 40%
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.

find the area of the shaded sector 12cm and 24°
3/10 are shaded.
3 shaded blocks out of 10 is 3/10, or .3
10/25 = 0.4 = 40%.
Area of the circle is about 10 square units
The fraction of shaded areas is 5/10 = 5 ÷ 10 = 0.5
Area of circle: pi*1.8^2 = about 10 square units
173
5 of 10 shaded would be 1/2 or 0.5 of the total number of squares.
10 / 25 = 4 *10 / 4 * 25 = 40 / 100 = 40%
