Answer:
The ladder reach a height 8.485 ft.
Step-by-step explanation:
The ladder with the building made right angle triangle
The length of the ladder is the hypotenuse 12 ft.
The angle between the ladder and the building is 45°
The height of the ladder reach is the vertical side of the Δ
∴ h = 12 cos 45° = 6√2 = 8.485 ft.
Answer:226.08 cubic feet
Step-by-step explanation:
π=3.14
Radius(r)=6feet
Height(h)=2feet
volume=π x r^2 x h
Volume=3.14 x 6^2 x 2
Volume=3.14 x 6 x 6 x 2
Volume=226.08
