step one on this problem would be to write the equation you need. [tex]V= \pi r^2 h \\ and \\ P=.03V[/tex] Pwould be Price, r your radius, h your hight, and V your volume. now lets plug them in [tex]109,422.72= (3.14) (24)^2 (60.5) \\ 3282.6816=(.03)(109,422.72)[/tex] therefor the answer would be $3282.68 or $3282.69 depending on if you always round up with money or not in your class (in the real world this is common). if you need help understanding plase let me know.
