## Please help: Carnot cycle

I'm trying to study for my physics test and I need help.

The problem is "A carnot engine operates with a cold reservoir temperature of 194 K and has an efficiency of 74.3 %. (A) What is the temperature of the hot reservoir? (B) If the engine does 8.99*10^4 J of net work during each cycle, how much heat does it absorb form the hot reservoir during a cycle?

I took the efficiency equation e=1-Tc/ Th and got 755 K for the first part of the equation, but I cannot seem to get the second part. Any suggestions??

How do you find out how much heat is absorbed by the hot reservoir during a cycle?
