<font face="Garamond" size="+2">


First thing to note:  "pie" is a dessert item, generally round in shape with a flaky pastry crust and frequently containing some sort of sweet filling, often made of fruit. "pi" is the English language representation of the lower case Greek alphabetic character used to represent the ratio between the diameter and circumference of a circle.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ V(r)\ =\ V\left(r(t)\right)\ =\ V(1.5t)\ =\ \frac{4}{3}\pi (1.5t)^3\ =\ \frac{4\cdot3.375}{3}\pi t^3\ =\ \frac{13.5}{3}\pi t^3\ =\ 4.5\pi t^3]
