Answer:

Step-by-step explanation:

To find the area of a sector, use this formula: (α/360) × πr²

α & r will be substituted by 120 and 3 respectively.

(120/360) × π(3²)

Step 1: 120/360 is equivalent to 1/3.

1/3 * π(3²)

Step 2: Square 3 to get 9.

1/3 * π(9)

Step 3: Multiply 9 by π to get 9π

1/3 * 9π

Step 4: Multiply 1/3 by 9π

The area of sector DEF in terms of π is 3π.
