Answer
$8,591.04
Explanation
In this question we shall find the volume of the cone as the first step.
Volume of a cone = 1/3 π r²h
where r = radius of the base and
h = height of the cone
∴ Volume = 1/3 × 3.14 × (12/2)² × 11.4
= 1/3 × 3.14 × 6² × 11.4
= 429.552 m³
Each cubic meter cost $20.
1,718.208 m³ will cost = 429.552 m³ × $20
= $8,591.04
