dw:1338436556319:dw this area?

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 \(16\pi\times \frac{7}{12}\)

When my teacher did it in class, it was much faster and more simple I just forget what he did..

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
 one year ago

satellite73Best ResponseYou've already chosen the best response.1
hold on degrees is a measure of an angle. area measures something entirely different

satellite73Best ResponseYou've already chosen the best response.1
the whole circle contains 360 degrees and you are missing 150 of them so you have left \(360150=210\) degrees

It's Area im trying to find sorry
 one year ago

satellite73Best ResponseYou've already chosen the best response.1
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

satellite73Best ResponseYou've already chosen the best response.1
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.
