In Part 3, we will touch on the outgoing energy from the planet, E_out, in relation to total energy balance.

So far, we've dealt with E_in and effective surface temperatures,T_eff , from incoming energy. Next, we need to explore Earth's released energy, E_out, and look at the overall energy balance of the experimental system.

Since a planet doesn't radiate energy in only one direction, but across the entire surface area (just like the sun), calculate the total surface area of the experimental / model planets (in m²).

Assuming that the radius is 0.75 cm
