The area of the whole pizza is:
+A+=+pi%2Ar%5E2+
For a 10" pizza, +r+=+10%2F2+
+A+=+pi%2A5%5E2+
+A+=+25pi+
The area of one slice is:
+A%5Bs%5D+=+%28+1%2F8+%29%2A25pi+
+A%5Bs%5D+=+9.8175+ in2
------------------------------
The length of the entire crust is:
+C+=+2%2Api%2Ar+
+C+=+2%2Api%2A5+
+C+=+31.416+
The length of one piece of crust is:
+C%5Bs%5D+=+%28+1%2F8%29%2A31.1416+
+C%5Bs%5D+=+3.927+ in
