Sagot :
Answer:
- 42390 ft³
Step-by-step explanation:
Since the tanks are congruent, they both have same volume.
If you rejoin them, it will form a cylinder with the radius of 15 ft and height of 120 ft.
The volume of the cylinder:
- V = πr²h = 3.14*15²*120 = 84780 ft³
The volume of each tank is half the volume of the cylinder:
- V(tank) = 84780 / 2 = 42390 ft³
- Radius=r=15ft
- Height=h=120ft
[tex]\\ \tt\Rrightarrow V=\pi r^2h[/tex]
[tex]\\ \tt\Rrightarrow V=\dfrac{22}{7}(15)^2(120)[/tex]
[tex]\\ \tt\Rrightarrow V=\dfrac{22}{7}(225)(120)[/tex]
[tex]\\ \tt\Rrightarrow V=42390ft^3[/tex]
