Determine the approximate value of a.
a) 18.11
b) 7.05
c) 7.95
d) 9.71

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

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:
