Please help me with my math

22.14

Step-by-step explanation:

Since perimeter is all around the easy part will be adding the trapazoids sides which add up as

11 + 4 + 4 = 19

when it comes to the semi circle you have to figure out the circumfrence

circumfrence = πd = π2

however because it is a semi circle you will need half of the circumfrence

π2 / 2 = π

so then you add the total to get

11 + 4 + 4 + 3.14 = 22.14

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.

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure
