Answer:
The area of the shaded sector is 144π square units.
Step-by-step breakdown:
Given:
The central angle for the sector is, 
The circle's radius is, 
The area of a sector with radius 'R' and angle 
can be determined with:
Substituting 
gives
Thus, the area of the shaded sector calculates to 144π square units.
Answer:
Refer to the detailed explanation below
Step-by-step explanation:
* Let’s organize the procedure to bisect angle ABC
- Angle ABC has vertex at point B and rays BA and BC
# Step 1:
- Center the compass at point B and draw an arc that crosses rays BA and BC ⇒ fifth step
# Step 2:
- Mark point D where the arc intersects ray BA and point E where it meets ray BC ⇒ third step
# Step 3:
- With the compass on point D, create an arc inside the angle ⇒ sixth step
# Step 4:
- Using the same compass width, set it on point E and draw an arc inside the angle ⇒ second step
# Step 5:
- Let point F be the intersection of the arcs from points D and E ⇒ fourth step
# Step 6:
- Draw a ray from point B through point F ⇒ first step
* This ray divides angle ABC into two equal parts
