Question

How do you get the arc length of a circle with 10 or 12 triangles in the inside?

Answer 1

radius is given ?
then may be you can use the formula :

arc length = \((\theta/360) * r \)

Answer 2

thank you

Answer 3

np...

Answer 4

oops! there is a mistake in the formula i have put

Answer 5

pls scratch my reply above

arc length is just this :
arc length = \(\theta * r\)

i think you can find \(\theta\) seen by arc by dividing number of triangles in the circle : \(360/n\)
