Question

If the measure of the ABC = 40o, which is the measure of arc AC?

Answer 1

80/360 * 2 pi r

Answer 2

angle AC makes wid the center is bouble of that with a point on circumference
hence the angle wid the center =80 degrees
hence arcAC=80/360 * 2*pi*r

Answer 3

so 80 is the answer
?

Answer 4

no 80*2*pi *r/360

Answer 5

80 is the angle at the centre.


U asked for the arc length.

Answer 6

yea but there is no given r so i am confused

Answer 7

r doesn't have to be given, u can just use r in the answer so it's

4pi r over 9 simplified.

Answer 8

i still dont get it.......

Answer 9

If u don't have an r that's all we can say.
