Answer:
$3364.65
Step-by-step explanation:
The volume of the cone is given by the formula ...
V = (1/3)πr²h
Filling in the given numbers, we find the volume to be ...
V = (1/3)π(1.5 m)²(7 m) = 5.25π m³ ≈ 16.49336 m³
The cost of the rice will be the product of this volume and the price per cubic meter:
cost = (16.49336 m³)($204/m³) = $3364.65
The cost of the rice necessary to fill the volume is $3364.65.

<em>Comment on pi</em>
If you use the value 3.14 for pi, the cost comes to $3362.94. A 3-digit value of pi only gives an answer good in its first 3 digits.
X percent = x/100
10 percent = 10/100 = 0.10
10% of $40 = 0.10*40 = 4
You save $4
The old price is $40 and changes to $36 after the discount is applied. This is ignoring any taxes or other surcharges
Anyways I'm going a bit off tangent. The final answer is choice B) $4
14850 is the average profit
and 18000 is the charge of $40
so 18000-14850 is your answer
