Why did you ask and post the answer within a minute of asking?

What you posted is the area of a circle.
{\pi} is the ratio of a circles diameter to its circumference.
In other words. The distance around a circle is Pi, or about 3.14, times the distance across it.
Area of a circle is {\pi}r^{2}
The radius is half the diameter.
Say a circle as a radius of 2 feet.
Its area is then {\pi}(2)^{2}=4\pi \approx 12.56 square feet.
Say a circle has a diameter of 2 feet. It's circumference is then 2\pi\approx 6.28
In other words, if the distance across the circle is 2 feet, then the distance around it is about 6.28 feet

A baked food composed of a pastry shell filled with fruit, meat, cheese, or other ingredients, and usually covered with a pastry crust.

Does the food necessarily be a circle! :eek:
And galactus, it's RickJ (if I'm not mistaken) who made this thread through the Go skin to test things out, that is the features in that skin.

Hello teste:
My math education STOPPED at pi. Interestingly, I've lived a whole life not know what it was, and I don't think I missed anything.

Of course it has to be a circle--- that's why the answer to "Pi are square" is "No they aren't, pi are round; cornbread are square!!"

I had a square pi once! :eek:

Okay. Now I want PI. Should it be apple? Raspberry? Lemon Merangue or Key Lime?

A quarter of each? :o
A quarter of each? :o
Wouldn't that be one-fourth?

Um... um... if you want to call it like that, no problem with me, it's the same, except that I don't use one fourth that often.

Oh, okay, a quarter then? :rolleyes:
Four of them makes a dollar! :eek:
