question 9a why must it be 10 to the power of 3?
1 km = 1000 cm = 1 * 10^3 cm
We will need to make the units the same before further calculation.

(25000)^2 = 6.25 * 10^8
9b they want the. answer to be in km
Oops my bad. Sorry missed that section.
2.5* 10^10 cm = 25 000 km^2
1cm^2 = (1000)^2 km^2 = 1.0*10^6 km^2
2.5* 10^10 cm = 25 000 km^2
1cm^2 = (1000)^2 km^2 = 1.0*10^6 km^2
