A circular oil spill has a radius of 2 miles. After a day, the radius of the spill increases by 3 miles. By how many square miles does the area of the oil spill increase?

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, i believe, but not sure.

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734
