Aspherical shell centered at the origin has an inner radius of 7 cm and an outer radius of 8 cm. the density, δ, of the material increases linearly with the distance from the center. at the inner surface, δ = 8 gm/cm3; at the outer surface δ = 10 gm/cm3. (a) using spherical coordinates, write δ as a function of ρ. use rho for ρ.
