During basic training Kevin learns how to read distances on a radar what should Kevin conclude is the distance around largest circle on the radar screen. Please help :(

H) 63.585

Step-by-step explanation:

Using the graph, we can estimate that the radius is about 4.5 units.

Using the formula of finding area of a circle, pi x radius^2, we can substitude 4.5 as r and 3.14 as pi.

So, 4.5^2 x 3.14 is about 63.585 units.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

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.
