Question

find the area of each sector. Use the 3.14 as the value of pi. Round your answer to the nearest tenth.​ Part 4

Answer 1

1) 378.1 in²

2) 8.4 m²

Explanation:

Area of sector=
`(θ°)/(360°) * \pi {r}^(2)`

1) Area of sector

`= (150°)/(360°) * 3.14 * {17}^(2) \\ = 378.1 \: in^(2) \\ (nearest \: tenth)`

2) Area of sector

`(60°)/(360°) * 3.14 * {4}^(2) \\ = 8.4 \: m^(2) \\ (nearest \: tenth)`
