All right i’m just behind and so yea

1. 1 & 3, and 2 & 4.

2. 3 & 2

3. 1 & 4

4. 1 & 2 and 3 & 4.

5. 1 = 3 and 2 = 4

6.  congruent.

7.  supplementary.

8.  congruent.

9. supplementary.

10. congruent.

11. congruent.

Step-by-step explanation:

1. Two pairs of vertical angles are 1 & 3, and 2 & 4.

2. The alternate interior angles from the diagram are 3 & 2

3. 1 & 4 = the alternate exterior angles.

4. 1 & 2 and 3 & 4 are the two pairs of corresponding angles are.

5.  The pair of angles that are congruent are 1 = 3 and 2 = 4 {Since, they are vertically opposite angles.}

6. Alternate interior angles = congruent.

7. Linear pairs are supplementary.

8. Corresponding angles = congruent.

9. Same side interior angles are supplementary.

10. Vertical angles are congruent.

11. Alternate exterior angles = congruent. (Answer)

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
