Pre-Algebra Lesson 11-1
Write the equation for the area A of a circle with radius r. Write the answer in
terms of pie

Area of a circle is given by:

A = πr²

This is one of the most commonly used equation in math and physic, so i recommend that you memorize this.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
