Answer:
12km or 12 kilometers
Step-by-step explanation:
We are given the following values:
For the first bearing we have:
30.3 degrees at a distance of 9 kilometers
We are asked to find the second distance of the second bearing at 40.3 degrees
Therefore, we have:
30.3 degrees = 9km
40.3 degrees = ?? Unknown( we designate this as y)
We crossmultiply
30.3 degrees × y = 9km × 40.3 degrees
Divide the both sides by 30.3 degrees
y = (9km × 40.3 degrees) ÷ 30.3 degrees
y = 362.7/30.3 degrees
y = 11.97029703 km
Approximately to the nearest tenth of a km
y = 12km.
Therefore, the distance of the plane from the mountain when the second bearing is taken (to the nearest tenth of a km) is 12km.
- Use the formula V = π <span>∙ r2 ∙ h.
- Plug into the equation. 27</span>π(cubed)=π∙3(2)∙h
-Solve. 27π(3)=9π∙h
27π/9π=3π
I believe the height is 3π.
