Question

What is the area of major sector DFE?

Answer 1

B. 171.69 cm²

Explanation:

Answer 2

B. 171.74 cm²

Explanation:

Area of a sector =
`(\theta)/(360) * \pi r^2`.

Where,

`\theta = 260`

radius (r) = 8.7 cm

Plug in the values into the formula

Area of sector =
`(260)/(360) * \pi 8.7^2`

Area of sector =
`(260 * \pi 75.69)/(360)`

Area of sector = 171.74 cm² (approximated)
