Let R be the region bound by the equations y = 2 + cos(x) and y = csc(x) in the first quadrant on the interval 0 ≤ x < π.

a) Write, but do not solve, an equation involving integral expressions whose solution is the area of

the region R.

b) Write, but do not solve, an equation involving integral expressions whose solution is the volume

of the solid generated when R is revolved around the x-axis.

c) Write, but do not solve, an equation involving integral expressions whose solution is the volume

of the solid generated when R is revolved around the line x = –1.

answer: true

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
