Yes Miranda, Earth is not a perfect circle. Its circumference is 95 miles longer at the Equator (24,901 miles) than it is around the poles (24,860) miles.

More precisely, Miranda, the Earth is not a perfect *sphere*.
A circle is a two-dimensional object-all points equidistant from a single point, in a plane.
A sphere is all points equidistant from a single point, measured in three dimensions-along the x-axis, y-axis, and z-axis.
Hat-tip to Euclid, and Mr. Johnson! Geometry was my favorite subject back in 9th grade.
