(A)

So you know:

A(t) = the integral of e^(-x) dx from 0 to t

and

V(t) = the integral of Pi*[e^(-x)]^2 dx from 0 to t

Just evaluate the integrals:

A(t) = -e^-t + 1

and

V(t) = -(1/2)*Pi*e^-2x + Pi/2

and then take the limits as t approaches infinity.

(B)

Just put V(t) over A(t) and take the limits.

(C)

I'm not sure what to do here though
