Answer:
7.1 (7.06 rounded to the tenth)
Step-by-step explanation:
The formula for Area of a Circle is: π·r²
R = Radius
π = pi, or 3.14
As long as you know the formula, this is easy!
In class, you may have already been told that the radius is <em>half </em>of the diameter.
1. Half of 3 ft is 1.5 ft.
2. Plug 1.5 in for r, in your calculator
3. Do the calculation, and you should come out to get 7.06858347058
4. Round it!
Finding area for a circle is satisfying, isn't it? xD
44,580 x 47 %
44,580 x .47 = 20,952.6
So, the water decreased 20,952.6 ft
If you want the water level after the drought just subtract.
44,580 - 20,952.6 = 23,627.4 ft
Hope this helps. :)
