Half-cylinder-shaped 31491

How many cubic meters of air is in an empty half-cylinder-shaped aircraft hangar if the hall is 30 m long and 12 m high at the highest point?

Correct answer:

V =  6785.8401 m³

Step-by-step explanation:

$$\begin{gathered} a=30\text{m} \\ r=12\text{m} \\ S=\pi \cdot r^2/2=3.1416\cdot 12^2/2\doteq 226.1947{\text{m}}^2 \\ V=S\cdot a=226.1947\cdot 30=6785.8401{\text{m}}^3 \end{gathered}$$
