Question

Find the length of the arc to 2 decimals places

Answer 1

Answer:

Step-by-step explanation:

The formula for arc length is

$AL=\frac{\theta}{360}*2\pi r$ where theta is the measure of the central angle and r is the radius. We have both of those pieces of info; filling in:

$AL=\frac{30}{360}*2(3.14) (4)$ and simplifying a bit:

$AL=\frac{1}{12}(8)(3.14)$ and a bit more:

$AL=\frac{25.12}{12}$ and finally, to

AL = 2.09 m
