Answer:
Step 1: Find the area of the entire circle.
The formula for the area of a circle is given by , where is the radius of the circle.
Given that the length of AC is 2ft, we can find the radius of the circle using the formula .
Now, we can find the area of the entire circle:
square feet.
Answer: Area of the entire circle square feet.
Step 2: Find the area of the sector .
The formula for the area of a sector of a circle is given by , where is the central angle in degrees and is the radius of the circle.
Given that the central angle measures 81°, and the radius is 1, we can find the area of the sector:
Answer: Area of the sector LACB= 9/40pie square feet.
