Celebrating Pi Day

Stephanie's math class is celebrating Pi Day today since it falls on a Saturday this year. I helped her make Rice Krispie spheres last night. The formula for finding the volume of each sphere is 4/3 times pi times the radius cubed. The surface area of each Rice Krispie sphere is 4 times pi times the radius squared.

And I was feeling all proud of myself because I took Onna out in a illness and medication induced haze and purchased a Cyrus O'Leary pie.

Dang you Hank!
