Question

HELP

Answer 1

• Radius=r=15ft
• Height=h=120ft

$\\ \tt\Rrightarrow V=\pi r^2h$

$\\ \tt\Rrightarrow V=\dfrac{22}{7}(15)^2(120)$

$\\ \tt\Rrightarrow V=\dfrac{22}{7}(225)(120)$

$\\ \tt\Rrightarrow V=42390ft^3$

Answer 2

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
