Precipitation and evaporation <span />
Astro Boy, by Osamu Tezuka
Answer:
21.5%
Explanation:
to find the answer to this equation you must found out how much each of the areas are
the circles area is represented by pi*(5^2)
that is 25pi
or
25 * pi = 78.5398163
then you find the area of the square
10 * 10 = 100 (5 + 5 = 10)
you can directly subtract 78.5398163 from 100 because it can be portrayed as 100%
100 - 78.5398163 = 21.4601837
you must round to the nearest tenth so your answer is
21.5%
And scientists say it will take natural processes 6,000 years to refill the reservoir
