Yep that is right. What fraction of the circle is the arc you have here?

pi(diameter) is correct for the circle but get used to 2pi(radius), that is a more common notation

should i use the formul.. l+ 2(pi)(r)(theta/360)?
 7 months ago

stupidinmath Group TitleBest ResponseYou've already chosen the best response.0
i mean l= 2(pi)(r)(theta/360)?

Andras Group TitleBest ResponseYou've already chosen the best response.1
You do not need that. Just forget the above 2 lines.

Andras Group TitleBest ResponseYou've already chosen the best response.1
You need the perimeter of the circle: 2pi(radius) and the fraction 1/4

oh, just that? to get the arc length?
 7 months ago

Andras Group TitleBest ResponseYou've already chosen the best response.1
That arc length has 1/4 of the perimeter of a full circle
