Correct Answer: Option B

Explanation

Area of a sector = \(\frac{\theta}{360}\) x \(\pi\)r\(^2\)

Area of a sector = \(\frac{50}{360}\) x 3.142 x 3.5 x 3.5

                           = \(\frac{50 \times 3.142\times 3.5 \times 3.5}{360}\)

                          = \(\frac{1924.475}{360}\) ≈ 5.346cm\(^2\)
