6,400 in Scientific Notation = 6.4 x 103
It is: 6.4*10^3
6.4 x 103
6400 = (6 x 1000) + (4 x 100) + (0 x 10) + (0 x 1)
Note that the number is same as 467000000.0. Shift 8 decimal places to the left from the starting point, so the exponent for base 10 is 8. Therefore, the number in scientific notation is: 4.76 x 108
Area of a sphere is (4) pi x r2. Since the earth's radius is about 6400 km then Area = (4) x pi x (64002) = 515,000,000 = 5.15 x 108 square kilometers
79% of 6400 = 79% * 6400 = 0.79 * 6400 = 5,056
