Pi Day Challenge And Happy Pi Day

There is an awesome challenge online. Since yesterday was pi day (March 14) they have something really cool.
www.pidaychallenge.com
3.14159265358979... Ok.
It's a series of levels where you have to answer lots of math questions.
Here are some of the questions below:
1. Name the first 5 decimal digits of pi.


3. (This is a trick question) What does the license plate say?

6A. The ___________ Theorem states that for any right triangle, the sum of the lengths equals the square of the length of the hypotenuse.

6B.
What is x?

9. What are the roots of the function

11. What is Archimedes' ratio approximation of pi?

I'm completely stuck on #23:
You run downwards at a speed of 3 steps per second.
It takes you 180 steps to get to the bottom.
You walk upwards at a speed of 1 step per second.
It takes you 20 steps to get to the top.
How many steps do you need if the escalator stands still?

Happy Pi Day and Thanks for the link

Is that the full statement of the problem?

Re: Pi Day Challenge And Happy Pi Day

It's all they tell me. There's another incomplete question. You have to find the area of the blue shaded area of a triangle with 10 equally tangent circles inside, but you can see the side or the radius.

Hi;


In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Re: Pi Day Challenge And Happy Pi Day

Thanks guys now I'm on 26; it's not an actual problem but a visual logic puzzle.
