Calculate the circumference of the circle. Use 3.14 for pi. I WILL MARK BRAINLIEST

The answer would be B

Step-by-step explanation:

C=2(pi)r

C=25.12

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
