Linking Can, Cylinders & Rational Equations.
Part A.) The volume formula for the coffee can is
h(3.14)r^2 = c
Part D.) You find the minimum cost by plugging in 2.4 for "r" (the radius) in the equation: .12(3.14)(r)^3+10.8/r = c. And this answer is logical because it is the Y value when you find the minimum of the parabola which is 6.67. Therefore, the minimum cost is $6.67 for the coffee can.
