I need help finding the lenght of an arc, can someone help me?

unklerhaukus · Answer

the circumference of a circle is $2\pi r$

the length of an arc over theta degrees is
$$2\pi r \times \frac{\theta°}{360°}$$

anonymous · Answer

The way the circle os portrayed, its a triangle being made, the aec being the base, and the angle on top is 18 degrees

unklerhaukus · Answer

for example, if the angle of an arc is 90°

$$L = 2\pi r \times \frac{90°}{360°}=2\pi r\times\frac14$$
