Find the circumference of the cylinder:
 circumference = 3.14 x 3.5 = 10.99 inches Round to 11 inches

the height is 14 inches

 so D 11" x 14" is correct

Does doubling the height of the cylinder has the same affect on the volume of a cylinder as doubling the radius explain
musickatia [10]
Volume of cylinder = π.R².h , where R = radius and h = height

Let's replace h by 2h:
V₁= πR².(2h) → V₁ = 2π.R².h

Now let's double R, the radius (and keep h as h)
V₂ = π.(2R)².h → V₂ = 4.π.R².h

Compare V₁ to V₂→ (V₁ = 2π.R².h  and  V₂ = 4.π.R².h).
It's obvious that V₂ = 2.V₁

A bag had 7 orange rocks , 6 green rock , 1 white rock ,7 black rocks , and 2 yellow you randomly pull a rock from the bag ,keep
daser333 [38]

Answer:

Probability = \frac{7}{253}

Step-by-step explanation:

Given

Orange = 7

Green = 6

White = 1

Black = 7

Yellow = 2

Required

Probability of selecting a yellow then orange rock

From the question, we understand that the probability is that of without replacement.

Since the yellow, is first picked.

We need to determine the probability of picking a yellow rock, first.

P(Yellow) = \frac{n(Yellow)}{Total}

P(Yellow) = \frac{2}{7 + 6 + 1 + 7 + 2}

P(Yellow) = \frac{2}{23}

The rock has reduced by 1;

Next is to determine the probability of picking an orange rock

P(Orange) = \frac{n(Orange)}{Total - 1}

P(Orange) = \frac{7}{7 + 6 + 1 + 7 + 2- 1}

P(Orange) = \frac{7}{22}

The required probability is calculated as thus:

Probability = P(Yellow) * P(Orange)

Probability = \frac{2}{23} * \frac{7}{22}

Probability = \frac{14}{506}

Probability = \frac{7}{253}
