Pi (π) is the ratio of a circle’s circumference to its diameter, which is approximately 3.14159 and thus the reason for designating March 14, 3/14, Pi Day.
Here’s a link to folk discussing all the things they plan on doing to mark Pi Day. I recommended that my husband, a math teacher, screen The Life of Pi for his students.
Last year I made a fruit tart to mark the occasion, but this year, I didn’t have the energy to cut up the fruit so I made a simple no-bake cheesecake and bought frozen strawberries:
8 oz Philadelphia Cream Cheese (softened)
1 (14 oz) can Borden’s Sweetened Condensed Milk
1/3 cup lemon juice
1 teaspoon vanilla
1 prepared graham cracker or shortbread crust.
Combine all ingredients with a mixer or a food processor until well-blended. Pour mixture into 1 prepared graham cracker or shortbread crust. Refrigerate overnight. Top with fruit or candy of your choice. Enjoy!
