Answer:

The volume of oblique cone having base radius 9 cm and height 6 cm is 1356.48 cm³

Step-by-step explanation:

Given: An oblique cone with base radius 9 cm and height 16 cm

We have to find the volume of the given oblique cone.

Consider the given oblique cone with base radius 9 cm and height 16 cm.

Volume of oblique cone = \frac{1}{3}\cdot \text{area of base} \cdot \text{height}

Finding first the area of base

base of oblique cone is circle so area of base = \pi r^2

area of base = \pi (9)^2=81\pi cm²

Substitute, we get,

Volume of oblique cone = \frac{1}{3}\cdot 81\pi \cdot 16

Volume of oblique cone = 27\pi \cdot 16

Volume of oblique cone = 432\pi

Using \pi=3.14 , we get,

Volume of oblique cone = 432 \times 3.14

Volume of oblique cone = 1356.48 cm³

Thus, the volume of oblique cone having base radius 9 cm and height 6 cm is 1356.48 cm³

Can I have help with this, I have drawn out a graph and marked my points so far.
Sidana [21]

Answer:

D. 2x²

Step-by-step explanation:

Ok, so the first thing to do is remember the first number in parentheses is x, and the second number is y.

You're trying to figure out which expression turns x into y in each set.

Just by plugging in the numbers into each expression I found that the answer is 2x².

I'll prove this starting with (1, 2).

1² = 1  

2 x 1 = 2

So, y = 2x²!

Next, (2, 8).

2² = 4

2 x 4 = 8

So, y = 2x²!

I'm not going to demonstrate with the other two but I hope you understand. Just plug the values of x and y into the equation and see which is correct.

I need help on this<br>​
Dvinal [7]

Answer:

1/12, 1/10

Step-by-step explanation:

P(Bead bracelet and red shoes) - 3/3 x 2 x 2

3/12=1/4 for bead bracelet

Red shoes - 1/3

Total probability for P(Bead bracelet and red shoes=1/4 x 1/3=1/12

P(Elastic bracelet and black shoes)

2/3 x 2 x 2

2/12=1/6 for elastic bracelet

Black shoes - 3/5

Total probablility for P(Elastic bracelet and black shoes)=1/6 x 3/5=3/10=1/10

Hope I helped!

Calculate the amount of heat (in kJ) released when 3.5 mol CH4 react. 4() + 22() → 2() + 22() + 890
In-s [12.5K]

The amount of heat (in KJ) released when 3.5 moles of CH₄ react is 3115 KJ

<h3>Balanced equation</h3>

CH₄ + 2O₂ -> CO₂ + 2H₂O ΔH = 890 KJ

From the balanced equation above,

1 mole of CH₄ reacted to release 890 KJ of heat energy.

<h3>How to determine the heat energy released by 3.5 moles of CH₄</h3>

From the balanced equation above,

1 mole of CH₄ reacted to release 890 KJ of heat energy

Therefore,

3.5 moles of CH₄ will react ro release = 3.5 × 890 = 3115 KJ of heat energy

Thus, 3115 KJ of heat energy were released from the reaction
