Step-by-step explanation:

The formula for the area of a circle is .

When you insert the numbers, you get

Hope this helped :)

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

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
