spin [16.1K]

Answer:

$14

Step-by-step explanation:

Assuming the cost of folder to be $x$ , then the cost of notebook will be $4 x$ and the cost of set of pencils will be $2 x$ .

Cost of the folder = $2

Cost of notebook = 4 × 2 = $8

Cost of pencil = 2 × 2 = $4

Total cost of 1 folder, 1 notebook and 1 set of pencils = $2 + $8 + $4 = $14

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 ro

Vlad1618 [11]

Answer:

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
