Question: pde heat euation plot

hello every one!

i have a pde problem( heat problem) i wanna plot it with maple and i know how can i solve it with maple but i wanna plot it and solve it with my boundry condition and initial condition then plot it

here my problem:

> with(PDEtools);
> PDE := diff(F(r, t), t)-.102*10^(-6)*(Diff(r*(diff(F(r, t), r)), r))/r = 0

now i wanna tell to maple that simplify my problem with F(r,0)=25 , F(.00004,t)=135

then plot the function between 0<r<.00004 and 0<t<30

i would be very greatfull if anybody help me...
