no it is not, it is called a sector? I think....
The circumference of a circle divided by its diameter is what
For a large enough sample, it will resemble a rectangle whose base will be the range of the variable and the height will be the reciprocal of the number (or width) of the base.
2 x pi x radius is used to calculate the circumference of the circle, when you know the radius. So, your sample problem should ask about some circle.
No, the sample mean and sample proportion are not called population parameters; they are referred to as sample statistics. Population parameters are fixed values that describe a characteristic of the entire population, such as the population mean or population proportion. Sample statistics are estimates derived from a sample and are used to infer about the corresponding population parameters.

The sample must have a high probability of representing the population.

Observations.
The general term statistics might be the set of numbers representing some sort of information from a sample population. The term data set can also be applied.
