I'm probably not going to bake a pi-themed pie today. Or any pie. So above is a screen capture from Google images.
On an earlier Pi-Day post, I calculated some useful pie-making numbers using π -- you probably remember them from basic math class: first the basic calculations. The area of a circle is π (approximately 3.14) times the radius squared. Therefore:
- 8 inch round pans have diameter 8, radius 4 so they have 3.14 x 4 x 4 = 50 square inches of area
- 9 inch round = 63.5 sq. in.
- 10 inch round = 87.5 sq. in.
Square pans have the following areas:
- 8 inch square = 64 sq. in.
- 9 inch square = 81 sq. in.
- 9 by 13 inch = 117 sq. in.
- An 8 inch square and a 9 inch round are virtually identical in their need for filling or batter.
- A 9 inch square and a 10 inch round are less than 10% apart.
- Two 8 inch squares are very close to a 9 x 13 inch rectangle.
- NOT equivalent: a 10 inch pie with sloping sides probably holds close to twice as much filling as an 8 inch pie.
UPDATE: the most extreme pie movie I've ever seen:
