What is the area of major sector DFE?
melomori [17]

Answer:

B. 171.74 cm²

Step-by-step explanation:

Area of a sector = \frac{\theta}{360} \times \pi r^2.

Where,

\theta = 260

radius (r) = 8.7 cm

Plug in the values into the formula

Area of sector = \frac{260}{360} \times \pi 8.7^2

Area of sector = \frac{260 \times \pi 75.69}{360}

Area of sector = 171.74 cm² (approximated)
