Question

Calculate the population within a 6 mile radius of the city center if the radial population

density is ρ(r) = 6(5+r2)1/3 (in thousands per square mile).

(Use decimal notation. Give your answer to two decimal places.)

Answer 1

Do you mean 6 (5+r^2)^(1/3) ????

dA = 2 pi r dr

dP = 2 pi r dr * [whatever you mean]
integrate from 0 to 6
