So the start of for this question, we know that our area is equal to 1 .5r squared theta.
00:07
Now, this will be necessary because we are trying to figure out the area that our blade will cover.
00:13
And so we know that our theta is equal to 120 degrees times pi over 180 degrees, because we need to convert into radiance.
00:24
It gets us 2 pi over 3.
00:27
And so then we can say for our total, so both our blade and our arm, our area is equal to one half times, let's see, we have 34 squared times 2 pi over 3.
00:42
And so then that will get us, let's see, 578 times 2 pi over 3, which will get us, let's see, 1 ,156 pi over 3.
01:05
We have just our arm, which we know our area is equal to 1 half, and our range...
