Find the area of the shaded region in this figure. Use the pie key for piew

i think its a and d

step-by-step explanation:

not sure but it may be b, as i said i'm not sure.

she will travel a distance in the range of 3 - 11 miles

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
