If QR is a median, then:

$\dfrac{NO+MP}{2}=QR$

We have NO = 30, MP = 9x - 42 and QR = x + 15. Substitute:

$\dfrac{30+9x-42}{2}=x+15\qquad\text{multiply both sides by 2}\\\\9x-12=2x+30\qquad\text{add 12 to both sides}\\\\9x=2x+42\qquad\text{subtract 2x from both sides}\\\\7x=42\qquad\text{divide both sides by 7}\\\\\boxed{x=6}$

<h3>Answer: A. 6</h3>

What is the volume of the cylinder? Round your answer to the nearest whole number??

andreyandreev [35.5K]

Answer:

141

Step-by-step explanation:

1. The volume of a cylinder is $\pi r^2h$ , where r = radius and h = height. In this case, the height is 5 feet and the radius is 3 feet.

Solving Volume

Step 1: Plug in values

$\pi * 3^2 * 5$

Step 2: Simplify.

$3.14 * 9 * 5$
$28.26 * 5$
$141.3$
141.3 ≈ 141

Therefore, the volume of the cylinder is 141 ft^3 (but don't put ft^3, as mentioned in the problem).

Have a lovely rest of your day/night, and good luck with your assignments! ♡
