A cone-shaped building has a height of 6 meters and a base with a diameter of 10 meters.

The building will be filled with road salt that costs $25 per cubic meter.

 

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

Use 3.14 for π

Round to the nearest hundredth.

Vcone  =  3.14 * (radius)^2 * height / 3

 

Vcone = 3.14  (5)^2 * 6  / 3  =      157 m^3

 

So....the total cost is    157 * 25   =  $3925
