The smaller sector is 360-255=105 degree
it is 105/360 portion of the whole circle, and the area of the whole circle is πr², r is 14
so the area of the smaller sector is (105/360)*π*14²
run those numbers through your calculator, use 3.14 for π, you get 179.5
if you are looking for area of the larger sector, it would be
(255/360)*π*14²=435.94
Add all the numbers together to find the total amount of college students surveyed.
355 + 292 + 280 + 191 + 198 + 136 + 66 + 24 = 1,542
The number is already simplified considering it's a whole number. The answer is either 1,542 or 1,500
<em>(I say either because when it says to simplify I'm not sure if they want it to be rounded.)</em>
18/25 is already simplified. There is no number that can go in both 18 and 25.
