    so total area if the radius is 4 is \(16\pi\) and you are missing a piece. the total number of degrees is 360 so you are missing a \(\frac{150}{360}\) of the circle leaving you with \(\frac{210}{360}=\frac{7}{12}\) of the circle

    your last job is to multiply \(16\pi\times \frac{7}{12}\)

    and the area of a circle with radius \(r\) is \(\pi r^2\) in this case \(\pi\times 4^2=16\pi\) so if a piece was not missing, the whole area would be \(16\pi\)

    4 times 150 = 600.. 600 / 360 = 120 degrees?

    so the only question is, what portion of the circle is left

    hold on degrees is a measure of an angle. area measures something entirely different

    the whole circle contains 360 degrees and you are missing 150 of them so you have left \(360-150=210\) degrees

    therefore you have what portion of the whole circle left shaded? it is \[\frac{210}{360}=\frac{7}{12}\] i.e you have seven twelfth of the circle left shaded

    • one year ago
  33. satellite73
    Best Response

    the entire circle has area \(16\pi\) and you have \(\frac{7}{12}\) of it left, so your area is \[16\pi\times \frac{7}{12}=\frac{28\pi}{3}\]

    You know what excuse my language. flutter math. All you need in life is Add Subtract Multiply and Divide. No, i'm not going to be a engineer, so needing all of this is out of the question. This kind of stuff does not work well in my brain. I feel it's unfair that us less fortunate people have to pay the price. Bad grades and getting spanked. No matter what I do I just dont get this stuff, I try really hard. I've been studying for this final exam for about 5 hours now, and I probably learned nothing. This is a load of crap and it's not fair. Sorry for wasting you time with this problem i'll be going to sleep now do to its 12:15 am here. Thanks.
