  1. Ms. Sue

    ??a cross that is 1 inch wide???

  2. Jennifer

    Crust*

  3. Ms. Sue

    A = pi * r^2

    A = 3.14 * 49

    A = ?

  4. Jennifer

    The answer has to be 40.8 in.

  5. Ms. Sue

    Why?

    3.14 * 49 = 153.86 = 153.9 square inches

  6. Jennifer

    Because I need to find the area of the crust not the whole pizza. The answers in the back on my book say it should come to 40.8 inches, but I don’t know how to solve it.

  7. Jennifer

    40.8 square inches*

  8. Ms. Sue

    A pizza crust has the same area that the whole pizza has.

    LOL, I think she just wants the part you see from above
    If D is 14 then the slimy area has diameter of 12 because you take and inch off each side.
    so
    area of a circle = pi d^2/4
    (pi/4)(14^2-12^2)
    sure enough 40.8

    Ahh -- thanks Damon.

  11. Jennifer

    Lol ok thank you!!
