Set up the iterated integral for evaluating modifyingbelow integral from nothing to nothing integral from nothing to nothing integral from nothing to nothing with upper d f (r comma theta comma z )dz r dr d theta∫∫∫df(r,θ,z)dz r dr dθ over the region d, where d is the solid right cylinder whose base is a region in the xy-plane that lies inside the cardioid r equals 2 plus 2 cosine thetar=2+2cosθ and outside the circle r equals 2r=2, and whose top lies in the plane z equals 6z=6.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2
