B Correct answer
Explanation

Area of sector = (1/2) * arc_length * radius = 0.5 * 2.2 * 3.5 = 3.85 cm^2.

AI explanation

The area of a sector can be calculated using the formula Area = (1/2) * radius * arc length. Substituting the given values gives Area = (1/2) * 3.5 * 2.2, which multiplies out to 7.7 divided by 2. The result is an area of 3.85 cm2.
