Calculate the active power
You'll notice that your circuit is nonlinear, due to the diode. Hence, if you want to know powers, you'll have to integrate the squared product of current and voltage over a period and then divide the thus calculated energy by the length of the period.
You seem to have a description of the voltage over time (although that graph isn't sufficiently labeled, so we don't know what we're looking at exactly; this might be the voltage over the diode, over the resistor, or over the voltage source), but you don't have a description of the current. You need to first find that definition of the current over time!
That might be very easy, or relatively complex, depending on how you model that diode. But it's something we can't do for you.
The rest should just be solving an integral. That's doable.
