Which one is correct?

B = 706.5

Step-by-step explanation:

here you are given the diameter you need to First find a radius and radius is half of the diameter which is equal to 30 /2 = 15

Area of the circle is

3.14× 15×15 = 706.5

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
