(adsbygoogle = window.adsbygoogle || []).push({}); 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)

c/d=3.14 the question reads

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&

find the radius....

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!
