Area of the circle = pi×r²
= 22/7 × 6 × 6
= 113.14 unit²
Answer:
sin -115° = -0.91
Step-by-step explanation:
Point A is (cos 115°, sin 115°). Since cos 115° = -0.42 and sin 115° ≈ 0.91, it means that the coordinates at point A is (-0.42, 0.91).
As for point B which was revolved around -115°,
the coordinates will be similar to point A but you just have to change the negative.
B(cos -115°, sin -115°) = B(0.42, -0.91)

Answer:
11196.15 km
Step-by-step explanation:
Consider the attached diagram
If the Airplane is at point A and the floating debris at point C, we want to determine the horizontal distance |AB| before they fly over it.
Using trigonometry

Cross multiply
|AB|X Tan 15 =3000
|AB| =
=11196.15 km
Therefore, the horizontal distance |AB| before they fly over it is 11196.15 km
