Final answer:
To find the volume of the island, set up a double integral in polar coordinates by expressing the given function in polar form. The conversion from Cartesian to polar coordinates is needed and then substitute the expressions into the given function. Setup the double integral using the values for r and θ to find the volume of the island.
Step-by-step explanation:
To set up the double integral in polar coordinates to find the volume of the island, we need to express the given function in polar form. The conversion from Cartesian coordinates (x, y) to polar coordinates (r, θ) is given by:
x = r * cos(θ)
y = r * sin(θ)
Substituting these expressions into the given function z = e^(-(x^2 + y^2)/4) - e^(-0), we get:
z = e^(-(r^2 * cos^2(θ) + r^2 * sin^2(θ))/4) - 1
Now we can set up the double integral in polar coordinates to find the volume V:
V = ∬ z * r dr dθ
Note: Please provide the limits of integration for r and θ to complete the calculation.
