Answer:
3π
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)
<em>Step 1: 120/360 is equivalent to 1/3.</em>
1/3 * π(3²)
<em>Step 2: Square 3 to get 9.</em>
1/3 * π(9)
<em>Step 3: Multiply 9 by π to get 9π</em>
1/3 * 9π
<em>Step 4: Multiply 1/3 by 9π</em>
3π
The area of sector DEF in terms of π is 3π.
