The diameter was of four half circles are sides of a square with a side length of 7 cm.
find the exact area of the shaded region in terms of pi. ( show work)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

b
