What is the approximate area of the circle shown?
use 3.14 to approximate pi. round your answer to the nearest hundredth. the diameter is 14

Area of circle  is 153.86 cm²

Step-by-step explanation:

Given : Diameter of circle is 14 cm.

We have to find the approximate area of the circle shown.

We know

Area of circle = π·r²

Given diameter = 14 cm

So radius is half of diameter.

So, radius = 7 cm

Thus, Area of circle = π·r²

Area of circle = 3.14 ·7²

Simplify, we have,

Area of circle = 153.86 cm²

Thus, Area of circle is 153.86 cm²

yes because a quadrilateral is equal to 4 sides and a rhombus has 4 sides so technacly it is a quadrilateral.

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.
