    Hint: area of slice = \(\LARGE \frac{x}{360}*\pi*r^2\) x is the angle in degrees r is the radius

    i don't understand how to use pi in equations

    what I would do is pull out the pi and ignore it temporarily

    In this case, x = 37 degrees and r = 10 if r = 10, then what is the value of r^2 ?

    so x*r^2 is 3700?

    so, \[\Large \frac{x}{360}*\pi*r^2 = \frac{37}{360}*\pi*10^2\] \[\Large \frac{x}{360}*\pi*r^2 = \frac{37}{360}*\pi*100\] then you can rearrange terms

    did you hold the command key and shift key, then press the "3" key? (the '3' over the 'w' and 'e') you should see a new pic file show up on your desktop

    sorry I don't know. None of the answer choices match what I wrote above, so I'm stumped. I think there's a typo maybe?

    does any of the answer choices have \(\Large 10^2\) in it?

    crud its not working its just pi*10*(37/360)

    or the 2nd one just with 10^2 instead of 10

    ok, so the "10" should be "10^2" because of the r^2 in pi*r^2

    so strange, it shouldn't be 10in^2 it should be 10^2 in^2 maybe that's what they meant?
