We are given
shape of volcano is conical
diameter=16km
so, radius=r=8km
height=h=1.95km
now, we can use volume formula
[tex] V=\frac{1}{3} \pi r^2 h [/tex]
now, we can plug values
and we get
[tex] V=\frac{1}{3} \pi (8)^2 (1.95) [/tex]
we can simplify it
and we get
[tex] V=130.69025km^3 [/tex]
so, approximate volume of volcano is 131 km^3.............Answer
