\textit{arc's length}\\\\ s = \cfrac{\theta \pi r}{180} \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=46\\ \theta =88 \end{cases}\implies s=\cfrac{(88)\pi (46)}{180}\implies s=\cfrac{1012\pi }{45}\implies s\approx 70.65

Answer:

Step-by-step explanation: 70.7

Given:

r=46

angle from arc =88

Formula and Explanation of formula:

You want to find the proportion/precent of the circle you want to find and multiply it by the full length of the circle, which is the circumference.


L=(Part of circle)/(full circle) Circumference\\\\\\L=(Part of circle)/(full circle) 2\pi r

Plug Given into Formula:


L=((88)/(360))(2)\pi (46) Plug into calculator

L = 70.7
