About 70% of Earth's surface is covered by water. If the diameter of Earth is about 12,750 km, find the area not covered by water to the nearest 100,000 km2.

Earth diameter = 12,750 km

Earth radius = 6,375 km

Sphere Surface Area = 4 • π • r²

Sphere Surface Area = 4 * 3.141 59 * 6375^2

Sphere Surface Area = 4 * 3.14159 * 40,640,625

Earth's Entire Surface Area = 510,704,724 square kilometers

Surface NOT covered by water = 510,704,724 *.3

Surface NOT covered by water = 153,211,417 square kilometers
