Question 1045149: A round pizza, with a diameter of 52 cm, is cut into 12 equal sectors. A square pizza, with sides of length 39 cm, is cut into 25 equal squares. Which pizza slice, a sector or square, has the greatest area and how much greater is it?

You can put this solution on YOUR website!
the area of the round pizza is:
+A+=+pi%2Ar%5E2+
+r+=+52%2F2+=+26+ cm
+A+=+pi%2A26%5E2+
+A+=+pi%2A676+
+A+=+2123.717+ cm2
---------------------
Each slice has an area of:
+A%2F12+=+2123.717%2F12+
+A%2F12+=+176.976+ cm2
-------------------------
The area of the square pizza is:
+A+=+39%5E2+
+A+=+1521+ cm2
The area of each square slice is:
+A%2F25+=+1521%2F25+
+A%2F25+=+60.84+
-----------------------------------
The area of each slice of the round pizza is
greater than the area of each slice of the
square pizza by the amount of
+176.976+-+60.84+=+116.136+ cm2
