No! Because I'm Stayin' Alive! Stayin' Alive!

We don't really have an official holiday for pi. It's like May the 4th. Big fans made May the 4th because when you say, "May the 4th be with you," it sounds like, "May the force." Us math people like joking about pi on March 14th because it's 3/14 like Pi, usually rounded to 3.14.

Also, you cannot see the full number of Pi because it goes on forever! It never ends. Sorry, but I can't show you.

If you think about this, we can easily figure out the radius. It might take some thinking, however. The area of a cylinder is [Area of Base]*Height, or, in this case, Volume= π*r²h. For this case, we need to find the radius. Usually people use this formula to find the volume, but since we already have the volume and height,  we can plug the values we have into the cylinder volume formula and use algebra to find the radius! 

In this case, I want to show you an EXAMPLE. Let's say that the height is 10 meters, and the volume is ≈ 125.66. We can plug these into the formula(let's also say that pi ≈ 3.14). Our formula, with the values plugged in, would equal 125.66= 3.14* r^{2 *} 1o.

Taking this, we can simply multiply 3.14r² by 10, giving us the new equation 125.66= 31.4r² 

We now simply divide each side by 31.4, giving us the equation(rounded to the nearest tenth), 4 = r². [The actual calculation was 4.00191082803, which cannot be rounded to the nearest tenth. Therefore, it became a whole number]

Now we can take the square root of each side to find the radius. 4= r^2 = {r=-2, r=2}. We know that, since we are talking about lengths, we can't have a negative length. Therefore, the radius(r)≈ 2, which was the number I chose when I planned the problem.

Hopefully this helps you realize that you can use the volume formula and work it algebraiclly to help you find a missing length in a cylinder.

More than none, less than ∞ . You're welcome

That's infront of the game console, actually. Maybe if your in-game character is on a mountain.

It doesn't help to only give the answer. They don't learn from that! Also give them the step-by-step, as someone else did. That is what helps!

You don't.

To input inverse tan(or inverse cos and sin), you can do multiple things:

1. Press the "2^nd" button and click "atan"
2. Press the shift key to trigger the "2^nd" button and click "atan"
3. Simply type "atan"
4. Simply type "tan^-1"

You can do the same for cos and sin, also! Hope this helps.

It did a lot.

Thanks for another way of doing it! The more ways there are, the more ways there are to verify an answer.
