Answer
$r=2000km\times\frac{100000cm}{1000km}=2\times10^{8}cm$
$h=3000m\times\frac{100cm}{1m}=3\times10^{5}cm$
$V=\frac{1}{2}πr^{2}h=\frac{1}{2}π(2\times10^{8}cm)^{2}(3\times10^{5}cm)=1.88\times10^{22}cm^{3}$
Work Step by Step
1. Convert the radius and thickness of Antarctica to centimeters.
2. Use to formula for the volume of a cylinder ($V=πr^{2}h$) and divide it by 2.
