---------------------------------------

One can of pumpkin pie mix will make a pie of diameter 8 in. If two cans of pie mix are used to make a larger pie of the same thickness, find the diameter of that pie. Use sqrt 2 is equal to about 1.414

**drwls**, Saturday, March 8, 2008 at 10:31pmThe volume of the larger pie will be double. Since the height of the filling is the same, the area will be double. To double the area, increase the diameter by a factor of sqrt 2 = 1.414.

Multiply 8 inches by that for the answer.

**Emily**, Saturday, March 8, 2008 at 10:51pmI'm sorry, but I don't understand what you mean by when you say "increase the diameter by a factor of sqrt 2 = 1.414." Can you please clarify for me? Thank you for helping me even though you're packing for a trip! =D

**drwls**, Sunday, March 9, 2008 at 5:50amI mean multiply 8 by sqrt2, which is 1.414. This gives you 8 sqrt2 = 11.31 inches

Compare the areas of an 8 inch pizza and an 11.31 inch pizza. One is twice the other.

Have fun on your trip!
