A small radio station can broadcast in a circular range with a radius of 20 miles. About how many square miles is the area covered by this range? Use 3.14 for \pi.

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

it would open into a square depending on the type of envelope i’m not sure about the second part
