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 salt

The answer to your question is  $ 8591.04

Step-by-step explanation:

Data

height = 11.4 m

diameter = 12 m

cost = $20/ft³

Process

1.- Calculate the volume of the cone

Formula

Volume = 1/3 πr²h

Substitution

Volume = 1/3 (3.14)(12/2)²(11.4)

Simplification

Volume = 1/3(1288.66)

Volume = 429.55 m³

2.- Calculate the cost

                $20 1 m³

                   x   429.55 m³

                   x = (429.55 x 20)/ 1

                   x = $ 8591.04

36÷48=0.75

0.75=

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
