Acone-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

The cost to fill the building with road salt is $ 8591.04

Solution:

Given that, A cone-shaped building has a height of 11.4 meters and a base with a diameter of 12 meters

Therefore,

Height = 11.4 meters

diameter = 12 meters

radius = 6 meters

Let us first find the volume of cone

The volume of cone is given as:

Where, "V" is the volume of cone

"h" and "r" are height and radius of cone

Substituting the given values, we get

Thus volume of cone is 429.552 cubic meters

The building will be filled with road salt that costs $20 per cubic meter

1 cubic meter = $ 20

Therefore, for 429.552 cubic meters, we get,

Thus cost to fill the building with road salt is $ 8591.04

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
