Much better, now I suppose the ball is in my court :-)

How many degrees "around" is a circle?

anonymous · Answer

360

whpalmer4 · Answer

Okay, and how much of the circle does sector C represent?

anonymous · Answer

0.35 so 35%

whpalmer4 · Answer

Right.  So what is 35% of 360 degrees?  (we're assuming that we have a perfect pie shape here, obviously we couldn't do this so easily otherwise)

anonymous · Answer

126 degrees?

whpalmer4 · Answer

For example, we couldn't do that in this drawing:|dw:1369590022115:dw|

whpalmer4 · Answer

Right!

anonymous · Answer

Thanks!

whpalmer4 · Answer

(sorry, I did my mental arithmetic incorrectly the first time, I was thinking 30% :-)

anonymous · Answer

Wait, so is 126 wrong?

whpalmer4 · Answer

No, 126 is correct.  The first time I computed it, I did 0.3*360 = 108, and started to ask you to check it, then I realized the problem is actually 0.35*360 and that does = 126, just like you got.

anonymous · Answer

Okay, perfect :)

whpalmer4 · Answer

Right, you were :-)

anonymous · Answer

I have a few more questions if that's okay @whpalmer4

whpalmer4 · Answer

Sure, but it's best to put them in new posts...

anonymous · Answer

Ok, I will do that then. Thanks.
