<p>Okay, so you have to find the area of circle B - circle C.
(Completely forget circle A… it’s there to confuse you).</p>

<p>Consider Circle B.
Radius: 2.5 units.
So, Area: (2.5)²∏ = 6.25∏ or 25/4∏</p>

<p>Consider Circle C.
Radius: 2 units.
So, Area: (2)²∏ = 4∏</p>

<p>Now subtract C from B.
25/4∏ - 4∏
= 2.25∏ or 9/4∏.</p>

<p>Makes sense? :slight_smile:
(Sorry for the ellipses instead of the circles… )</p>

<p>This question took me like 1 minute first… and then I had to come back to it because first I chose 5pi… then I thought the figure IS drawn to scale and 5pi doesn’t seem right.</p>

<p>Phew!</p>

27

<p>Lol, thats pretty funny.</p>

28

<p>How about that question that asked about the slope of the line (and the line was tangent to the circle, and like it was 5,t or something like that?</p>

29

<p>5/4 asddsaasd</p>

30

<p>@Any… the answer was 1/2 or 0.5</p>

31

<p>Eh? Wasnt it 5/4?</p>

32

<p>^ They’re talking about last free response.
Yes, one of the slope answers was 5/4.</p>
