A cone-shaped building has a height of 11.4 meters and a base with a diameter of 12 meters. The building will be filled with road salt that costs $20 per cubic meter.

How much will it cost to fill the building with road salt?

Use 3.14 for π.

Verified Answer :

We know, Volume of a Cone = πr² h/3
v = 3.14 (6)² 11.4/3
v = 3.14 36 3.8
v = 429.552

Now, for 1 m³, it costs = $20
So, for 429.552 m³, it will be: 20 * 429.552 = 8591

In short, Your Answer would be $8591

Hope this helps!
