What the hell is this they didn’t teach me this help me

C

Step-by-step explanation:

Area = π

r means radius

radius = d/2

d = diameter

8 /2 = 4

4 is radius

= 16

^ ( its 4 x 4 ) ^

so then,

Area = 16π

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
