Step-by-step explanation:
The central angle measure of the sector is 4.19 rad.
<h3>Area of a Sector</h3>
You need apply the formula:
for finding the area of the sector, in radians. In this formula, the variables are:
r= radius
= central angle
The question gives:
A=54
cm²
r= radius= 9cm
Thus, the central angle will be:
![A= r^2*\frac{\alpha}{2}\\ \\ 54\pi =81*\frac{\alpha }{2} \\ \\ 1.33333\pi =\alpha](https://tex.z-dn.net/?f=A%3D%20r%5E2%2A%5Cfrac%7B%5Calpha%7D%7B2%7D%5C%5C%20%5C%5C%2054%5Cpi%20%3D81%2A%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%5C%5C%20%5C%5C%201.33333%5Cpi%20%3D%5Calpha)
For
=3.14159..., you have :
![\alpha=4.19\; rad](https://tex.z-dn.net/?f=%5Calpha%3D4.19%5C%3B%20rad)
