which equation is needed to determine the volume of the given figure?

Answer:
[tex]v = \pi \times {r}^{2} \times h[/tex]
Step-by-step explanation:
height=11km
diameter=10km
radius=diameter÷2
=10÷2
=5km
now,
volume=
[tex]\pi \times {r}^{2} \times h \\ \frac{22}{7} \times {5}^{2} \times 11 \\ \frac{6050}{7} \\ 864.3 \: {km}^{3} [/tex]
