Help! The shaded sector below has am area of 4pi. FInd the perimeter of the sector
15 Points!

10.19

Step-by-step explanation:

40°=360°/9=2π/9

area of circle= πr²

Area of sector= πr²/9

P circle= 2πr

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
