We can parameterize this part of a cone by

with

and

. Then

The area of this surface (call it

) is then
If your solving for B then its B<43/3
The question is missing the figure. So, it is attached below.
Answer:
Area of the shaded sector is <u>144π units squared</u>.
Step-by-step explanation:
Given:
Central angle of the sector is, 
Radius of the circle is, 
We know that, area of a sector of a circle of radius 'R' and central angle
is given as:

Plug in
. This gives,

Therefore, the area of the shaded sector is 144π units squared.
