Figure 20.47

(a) What is the time constant?

(b) How long will it take to reduce the voltage on the capacitor to 0.350% of its full value once discharge begins?

(c) If the capacitor is charged to a voltage V0 through a 125 resistance, calculate the time it takes to rise to 0.865V0 (this is about two time constants).

I got part a and b... but i dont know how to get part c! a is 22.1s, part b is 125 s....
