What is the volume of the cylinder if the height is 2x+7 and the radius is x-3

shusha [124]

Answer:

Therefore the volume of the cylinder $=\pi(2x^3-5x^2-24x+63)$ cubic units

Step-by-step explanation:

Given height of a cylinder is (h) =2x+7

and radius (r)= x-3

Volume of the cylinder = $\pi r^2 h$

$=\pi (x-3)^2(2x+7)$

$=\pi (x^2-6x+9)(2x+7)$

$=\pi (2x^3-12x^2+18x+7x^2-42x+63)$

$=\pi(2x^3-5x^2-24x+63)$ cubic units

Therefore the volume of the cylinder $=\pi(2x^3-5x^2-24x+63)$ cubic units

Please help, I’m not sure what the answer is.

Karo-lina-s [1.5K]

Answer:

The answer is 'C'

Step-by-step explanation:

Congruent simply means "the same." When a line divides two parralel lines transversals are created. This means that there are angles on both lines that are similar. To fully understand which angles would be the same, I reccommend researching "transversals" for more information, or asking your teacher about it as it is hard to explain without a proper diagram.

Rewrite as a simplified fraction. 2. 14 ‾ = ?

SOVA2 [1]

Answer:

1/7

Step-by-step explanation:

- I can't really tell what the fraction you have is, I am assuming it is 2/14. If that is correct, simplify by finding a common number.

- Ask yourself, what can both be divided by? (Answer is 2)

- Knowing both simplify by 2, divide the numerator (top) and denominator (bottom) by 2.

- You should get 1/7 (2/2 = 1 and 14/2 = 7)

- If you have any further questions on this topic please let me know. I would be glad to help anytime!
