Can someone please answer this for me I need it quick! I don't wanna fail and I need to show my work.

1. 37699.1

2. 14.1

3. 9202.8

4. 1734.2

Step-by-step explanation:

1.

radius is 20

height is 30

π * 20^2 * 30 = 37699.08

Rounded to nearest tenth is 37699.1

2.

radius is 1.5

height is 6

(1/3) * π * 1.5^2 * 6 = 14.13

Rounded to nearest tenth is 14.1

3.

radius is 13

(4/3) * π * 13^3 = 9202.76

Rounded to the nearest tenth is 9202.8

4.

There is a cone and a cylinder

cone:

radius is 6

height is 10

(1/3) * π * 6^2 * 10 = 376.99

Rounded to the nearest tenth is 377

cylinder:

radius is 6

height is 12

π * 6^2 * 12 = 1357.16

Rounded to the nearest tenth is 1357.2

Add them together

377 + 1357.2 = 1734.2

3x + 2y = 12

Step-by-step explanation:

Same thing, just changed the coefficient which was 6. If the inf. solution is inf, it can literally be anything.
