EST... Coffee started at 7:00.
Okay...The term Pi is pretty easy, but the truth shall be known soon.
Q: When you need to use Pi in an equation, but your calculator is too cheap to have the button for it...<span style='color:crimson'>How can you still calculate the value for Pi?</span>
Sounds simple enough...We'll see who has the right answer.
Q: A real life example: You are going to renovate a chimeny on a two story house, but need to determine how much scaffolding to rent. You don't have any blueprints or specs to look at, and you only have a 15' tape measure.<span style='color:crimson'>How do you calculate the height of chimeny?</span>
This will finish this debate.

Welcome Mrs. R
hows about a pic of the 2 of u?

Q1: 22/7 is a good approximation, but only to a couple of decimals, so it's generally easier to just memorize about 5 decimal points. Anything more than that usually has no effect on the answer you calculator will give you. I seem to recall that there's also a conversion based in radii... but I can't remember it at the moment.Okay...The term Pi is pretty easy, but the truth shall be known soon.

Q2: You underestimate my hubby. I'm pretty sure he know's the pythagorean theorem. Measure the approximate angle of the sun above the horizon and measure the distance of the shadow. Then multiply the tangent of the angle by the measure of the shadow... the result should be the height of your chimney. As a shortcut... watch your morning news and find out what time sunrise is. Find the time that is halfway between sunrise and noon (or equivalently halfway between noon and sunset). At this point in time, you should have about a 45 degree angle, allowing for the time of year and assuming you aren't in antarctica or northern Canada, so the length of the chimney's shadow should be pretty close to the actual height. Close enough for government work, at least.

Do you always quiz new board members so intensely?
Or am I getting special treatment?

Oh, I believe you're getting the Super Special treatment Mrs. R...first time these guys get to play with a SMART gal!
Actually, you just hit an intellectual vein in the board...signed on at just the right time...lucky you...
Sorry Mrs. Revlis, but your hubby said to ask you a math question.
On Q2, I was actually just looking for the use of the Tangent equation. If you measured out from the base of the chimeny to a point some distance away, this would be the "Adjacent" side, and then using the protractor to measure the acute angle to the tip of the chimeny (Theta), you now have two out of the three variable in the equation. Now you just solve for the unknown variable, which is the "Opposite" side, and also the chimeny height.
It's cool to know/learn about using the sunrise/noon measurement approach. I hadn't thought of that method.
Note: My daughter is currently going through this stuff in her High School class, so it was fresh in my mind. I'm more of a Physics nut than math, but they work together so I don't mind.

Um, as it relates to "Stkr00" and his second question? Your Both Full of Shid and here is why.
I need some masonry work done on my chimney? I pick up the phone, and I call a Gen. Contractor friend of mine, explain what I need done, Kurt in turn calls the Mason and he comes out with the right tools and years of experiance to handle the job and we get it done. Simple.
So if I need to know the height? I say "Dude, so how tall is that bad boy anyway? Then I write him a check and we're good to go... Problem solved.

Ok... Mrs. SilveR,
Describe the Fibonacci numbers and where they came from... Perhaps even touching base on the golden ratio!
Did I stump ya?

uh huh. So, you need time to look it up. I see how you operate!
