In circle M with angle LMN = 60 and LM = 15 units, find the length of arc LN.  Round to the nearest hundredth.

Hi Guest!

Try to perhaps screenshot problems in the future so it's easier to read.

If LM is 15, then the circufremce of the circle is 30pi.

60 degrees is 1/6 of the cricle, so the answer is 30pi/6 = 5pi.

I hope this helped. :)))

.

There are 360 degrees in a rotation and you have 60 of them in this arc

so

arc length =  $$\frac{60}{360}*circumference\\ =\frac{60}{360}*2\pi*15$$
