Antarctica is roughly semicircular, with a radius of 2000km. The average thickness of its ice cover is 3000m. How many cubic cm of ice does Antarctica contain? (Ignore the curvature of Earth).

• physics 1 -

V = (1/2)*pi*r^2*(thickness)
r = 2*10^8 cm
thickness = 3*105 cm
The answer will be in cm^3 if you use these units.
