Python includes many useful modules that are just an import away. The math module is extremely useful in computing mathematical expressions in Python. Suppose we want to very accurately compute the area of a circle with a given radius. (Here's the link if you don't remember the formuta).
Get the radius as an input from the user Notice that we need the constant pl which is roughly 3.14 Conveniently, the math module has p defined for us as math. pi Use it to compute the area.
Output the resulting area with five digits after the decimal point.

this seems to be in the wrong category. but i'll take some free points my dude

posting this in wrong category will result in people seeing it who won't know the answer.

solution:

the auto-correct option of the auto-correct tool enables you to add and delete words that do not follow abbreviation rules because:

it is a feature that allows outlook to correct common spelling and typing errors and to replace characters with symbols. we can also can use auto-correct as a shortcut, which means we can type a small string of characters and have those characters replaced by a longer string.
