Assuming you're just computing the volume, i.e.

we should convert to cylindrical coordinates first, setting

so that the volume is given by

which has a value of

.
Answer:
AB and CD are parallel lines
Step-by-step explanation:
• Parallel lines have equal slopes
• The slopes of perpendicular lines are negative reciprocals
Calculate the slope m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
let (x₁, y₁ ) = A(1, 4) and (x₂, y₂ ) = B(3, 8)
m =
=
= 2
let (x₁, y₁ ) = C(- 1, 6) and (x₂, y₂ ) = D(3, 14)
m =
=
= 2
Since slope of AB and CD are equal then lines are parallel
The correct answer is the letter B
