Help me continue. topic: circumference, polygons..
Find the circumference of the circle inscribed in a regular hexagon with sides 18cm long.
I should find the radius... how? |dw:1389280808018:dw|
ugh. i dont know. help
|dw:1389281105829:dw|
the proportions of any 30-6090 degree triangle, are |dw:1389281244706:dw|
hypotenuse is twice the smaller leg, and half of the hypotenuse is the radius. and then use \[C=2πr~~~~~~~~~or~~~~~~~~~~~~~~C=πd\] (Because d=2r )
oh, thank you soo soo much! :)
Anytime, also if you ever see |dw:1389281509527:dw| for 45 45 90 degree triangle... you welcome!
will remember that. thanks again :))
