Answer:
D. 158.4 km²
Step-by-step explanation:
Area of sector = θ/360 * πr²
Where,
θ = 150°
r = 11 km
Substitute
Area = 150/360 * π * 11²
Area = 158.38863 ≈ 158.4 km² (nearest tenth)
1/12 is the square root of 1/144
9514 1404 393
Answer:
y = 2
Step-by-step explanation:
The variable x can be eliminated by subtracting the first equation from the second.
(-x +4y) -(-x -y) = (15) -(5)
5y = 10 . . . . . . . simplify
y = 2 . . . . . . . . . divide by 5
