Carissa also has a sink that is shaped like a half-sphere. the sink has a volume of 2000/3[pie] in^3. one day, her sink clogged. she has to use one of two conical cups to scoop the water out of the sink. the sink is completely full when carissa begins scooping. (a) one cup has a diameter of 4 in. and a height of 8 in. how many cups of water must carissa scoop out of the sink with this cup to empty it? round the number of scoops to the nearest whole number. (b) one cup has a diameter of 8 in. and a height of 8 in. how many cups of water must she scoop out of the sink with this cup to empty it? round the number of scoops to the nearest whole number. asap! be sure answer is 100% correct!

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.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
