Final answer:

To find the volume of the volcano, set up a triple integral in cylindrical coordinates with appropriate limits of integration for z, rho, and theta. Then, integrate the expression to calculate the volume.

Step-by-step explanation:

To find the volume of the volcano, we first need to determine the limits of integration for the z-coordinate. The graph z = 1/(x^2 + y^2) represents a hyperboloid that extends from z = 0 to z = 1. The cylinder x^2 + y^2 = 1 encloses the hyperboloid.

To calculate the volume, we can set up a triple integral in cylindrical coordinates:

V = ∫∫∫ dz dρ dθ

The limits of integration for ρ and θ are 0 to 1 and 0 to 2π, respectively. The limits of integration for z are 0 to 1/(ρ^2) since z = 1/(x^2 + y^2).

Thus, the volume can be calculated as:

V = ∫V dz = ∫ (∫ (∫ dz) dρ) dθ = ∫ (∫ (1/(ρ^2)) dρ) dθ

Integrating this expression will yield the volume of the volcano.
