Find the area of the entire slice of pizza. Since the slice of pizza is part of a whole pie, let’s think of the pizza as a sector of a circle. Calculate the area. Be sure to show all of you work.

the radius of the circle is 6 so area of the whole pizza is pi * 6^2 = ? now you need to find out how many pieces of pizza are in the whole pizza this equals 360/45 = x so divide the area of the whole pizza by x and you'll get it.
113.04 is area of whole pizza
8 pieces
so the answer would be 14.13
right so area of 1 pizza clice = 113.04 / 8
14.13
right
then I have to do this for my next part of the questionFind the area of the pizza without the crust. We can use our knowledge of triangles for this step. Given that the height of the triangle is 5.5 in. and the base of the triangle is 5 in., calculate the area. Show all of you work
what did you use for pi , 3.14?
i got the answer too Area of a triangle = ½ base x height Area of triangle = ½ 5 x 5.5 Area of triangle = 13.75 in squared
looks good
thn can you help me with the are of the crust? would i just subtract 13.75 from 14.13 to get the answer?
yes i used 3.14 for pi
yes
so the are is only .38?
right
that seems really small though
i got 113.097 for the area of whole pizza because i used pi on my calculator but if you usually use 3.14 in class thats ok.
thin crust! well you have your calculations right
ok thank you
