Answer: Well i think when she first starts the business they cost for haircuts dont cost that much but as she gains more popularity the price for her haircuts rise giving her more money
Step-by-step explanation:sorry if im wrong
Answer:
r = 3.628 cm
h = 10.88 cm
cost = 11.16 cents
Step-by-step explanation:
we know the total volume = 450 cc
then pi * r ^ 2 * h = 450
solved for h:
h = 450 / (pi * r ^ 2)
h = 143.31 / r ^ 2
now the total cost of packing = 2 * 3.14 * r * h * 0.03 + 3.14 * r ^ 2 * 0.03 + 3.14 * r ^ 2 * 0.06
= 0.1884 * r * h + 0.0942 * r ^ 2 + 0.1884 * r ^ 2
= 0.1884 * r * h + 0.2826 * r ^ 2
putting the value of h in the previous equation we obtain
total cost = 27 / r + 0.2826 * r ^ 2
we have to minimize this to differentiate it and equate it with 0
:
-27 / r ^ 2 + 0.5652 * r = 0
r ^ 3 = 27 / 0.5652
r ^ 3 = 47.77
r = 3,628 cm
replacing:
we get h = 450 / (3.14 * 3,628 ^ 2) = 10.88 cm
the total cost can be calculated for the equation
we get the total cost = 27 / 3,628 + 0.2827 * 3,628 ^ 2 = 11.16 cents
