insulator and conductor problem?

A cylindrical conducting shell is placed concentric with a cylindrical insulator. Assume that a total charge density λ0 = -2.80 µC/ m is placed on the inner cylinder and a total charge density λ = 3.50 µC/ m is placed on the outer one, r0 = 7.30 cm, r1 = 14.60 cm and r2 = 18.80 cm. Calculate, relative to r = 10·r0 = 73.0 cm:the electric potential at r = 54.60 cm.
cylindrical conductor: E=2kλ /r when r>r0
cylindrical insulator: (r (r>r0) E=2kλ/r
