If pizza P has a diameter of 28 inches, it’s approximately 28 * 3.14 inches around, or 87.96 inches. That’s more than 7 feet of crust-cumference! (Courtesy of Mike Cain)

If this little rhyme brings back anxieties from middle school algebra class, don’t despair. This year, the Maryland Science Center is celebrating Pi Day — the annual celebration of the mathematical constant pi — the right way: with pizza and baked goods.


To find the approximate volume of your slice of Key Lime heaven, figure out multiply pie height H by the area of the pie divided by the number of slices, N. Volume = H(πR^2/N). Or you could just eat it maybe, I think it’s getting warm. (Tracy A. Woodward/THE WASHINGTON POST)

The festivities kick off at 10 a.m. Wednesday — March 14, or 3/14, corresponds to the first three digits of Pi — and include a pie-eating contest, a pizza pie toss, a pi recitation contest, pi-themed crafts and a search for circular objects in the museum.

Pi is the ratio of a circle’s circumference to its diameter.

If the Maryland Science Center, located in Baltimore, is a little out of the way Wednesday, here are ways to nerd out in the D.C. area:

Pastry party: Local blogger/baker Emily Hilliard of Nothing in the House is teaming up Wednesday with Radio CPR DJs to host a Pi(e) Day party in Mount Pleasant. Expect live music, DJs, a pi(e) walk, and all-you-can-eat pie.

Pi Day, It’s Pi Day…: Lounge 201 in Northeast is hosting a Pi Day party featuring pies from Georgetown’s Pie Sisters and pizza from District of Pi.
