Write a MATLAB script to implement the following: A glass has the shape of a truncated cone of height $8$ inches. Its top radius r$2$ is $6\mathrm{.}2$ inches and its base radius r$1$ is $4\mathrm{.}8$ inches. If water is poured into the glass at $2$ gallons per minutes, write a script to calculate how many seconds it takes to fill the glass to the brim. One cubic feet is $7\mathrm{.}5$ gallons.
