A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 \text{ cm}30 cm30, start text, space, c, m, end text, and the bicycle wheel makes 333 full rotations before stopping. How long is the trace of water left on the floor? Round your answer to the nearest

186 cm

Step-by-step explanation:

Since the bicycle wheel is making a rotation and not a revolution, the bicycle wheel is at one point.

The length of the trace of water left on the floor is simply the circumference of the bicycle wheel

Circumference = 2πR

where R = radius of the bicycle wheel

and π = pie

Circumference = 2 × (22/7) × 30 = 188.57143 cm

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.
