Answer:
<u>395.64 m³</u>
Step-by-step explanation:
<u>Volume (figure)</u>
- Volume (hemisphere) + Volume (cylinder)
- 2/3πr³ + πr²h
- πr² (2/3r + h)
- 3.14 x 9 (2 + 12)
- 3.14 x 9 x 14
- 3.14 x 126
- <u>395.64 m³</u>
Working conditions in the United States in the early 1900’s can best be described as atrocious.
Step-by-step explanation:
Let θ be the angle of depression i.e the angle between the horizontal and the observer's line of sight.
tanθ= (Height of the light house)/(Horizontal distance of ship from the base of light house)
∴tanθ=88/1532=0.0574
∴θ=tan−1(0.0574)=3.290(2dp)
