Acollar of styrofoam is made to insulate a pipe. find its volume. the large radius r is to the outer rim. the small radius r is to the edge of the insulation. use pi almost equals 3.14 .π ≈ 3.14. r = 55 in. r = 77 in. h = 1515 in.

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
