Answer:

- 18m² - 4m - 16

Step-by-step explanation:

2B - 2A

= 2(- m + 1 - 9m²) - 2(m + 9) ← distribute both parenthesis

= - 2m + 2 - 18m² - 2m - 18 ← collect like terms

= - 18m² - 4m - 16 ← in standard form

1. volume of a cylinder = pi x radius squared x height (I wasn't sure which was the radius/diameter)

2. 615.74

3. 1km

4. rearrange formula for volume of the cylinder to get the radius on 1 side. divide both sides by height and pi to leave u with r². then divide by the square root.

formula= r=square root of 3080³/3.14 × 20

5. height = volume/ pi x radius squared

6. 2463.01

7. 28.01

8. 145.955 m
