Question

What is the arc length of the arc subtended in a circle with radius 6 and an angle of 7

8 ?

Answer 1

consider arclength so be a division of circumference

Answer 2

ok thanks

Answer 3

since the circumference of a circle is simply: 2pi r

the percentage of that which is related to \(\theta\) degrees is: \(\theta\)7 out of 360, or simply a multipler of \(\theta/360\)

\[\frac{\theta}{360}~2\pi~r\]

Answer 4

oh ok i see now thanks
