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.
