square kilometers
Step-by-step explanation:
The surface area of a sphere can be found using the formula 
. Since the diameter is 3500 km then its radius is half of this. 3500 divided in two is 1,750 units. Substitute r=1,750.
The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base.
