# Circles and pie

circles.... and pie

ok so i found this site and im learning about circles now :) http://www.mathgoodies.com/lessons/vol2/circumference.html

it says pie is 3.14 which is what you get when you divide the outer measurement of the circle by the diameter (pie being 3.14 as per his homework)

in this problem i have used & to mean pie cuz i don't know how to make that symbol
circumference of a circle is 6&

so

6&/d=&

6(3.14)/d=3.14
18.84/d=3.14
18.84=3.14d
18.84/3.14=d
6=d
diameter is 2x radius so raidus is 3

sound right?
thanks again guys and gals!

Its right.

You couldve saved some time by dividing both sides by pi in the first step

Just for reference, it is written pi. You can get the pi symbol by using LaTeX code. You write tex or itex in brackets and close them with /tex or /itex in brackets. Write \pi inbetween the code to get the symbol to show up.

Like this: $$\pi$$, click the symbol to see the code to write it.

I like pie :tongue2: However, I believe you are referring to the mathematical constant which whozum correctly spelled pi ..

If you want to make the symbol $$\pi$$ click on the one I made and a popup window will show the syntax you can use, to create it)

(while I was writing this, i see Candyman has a similar suggestion, I wonder if he/she also likes pie :tongue2: )
