Answer:
2 feet per year
Step-by-step explanation:
First, we need to find the amount it grew:
13 - 3 = 10
So between 2005 and 2010 it grew 10 feet.
Now to find the yearly growth we need to divide the distance by time:
10 ÷ 5 = 2
So it grew 2 feet per year.

Answer:
67 million square miles
Step-by-step explanation:
The area of a sphere is given by ...
A = 4πr²
So the area of the Earth is approximately ...
A = 4π(4000 mi)² ≈ 2.01×10^8 mi²
The area of the 1/3 that is not covered by water is approximately ...
(2.01×10^2 mi²)/3 = 6.7×10^7 mi²
The land area is estimated to be about 67 million square miles.
