## Homework Statement

Compare this to the power received on the ground from a geostationary satellite with a 1 W transmitter and with a transmission footprint of 1000 square km across (assume uniform power in footprint).

## The Attempt at a Solution

I don't know where to start on this one pretty much. I mean I know that it is transmitting 1 W of power and that the intersection of this beam with the Earth's surface is 1000 square km, but I just don't know how I would go about determining the total power collected. There must be something that I'm missing because from the amount of marks allocated for this question you wouldn't receive 1 W of power. Any hints on what to do would be greatly appreciated.

Cheers
