<PRE><B>Question 159140</B>
if the diameter of the well is 6 feet, then it&#39;s radius is 3 feet.
R = 3 feet
-----------------------------
water is 7 feet deep
------------------------------
volume of water in the well is pi*R^2*h.
this becomes pi*9*7
pi = 3.141592654
volume of water in the well becomes 197.9203372 cubic feet
--------------------------------
there are 7.48 gallons of water to a cubic foot.
number of gallons in the well = 197.9203372 / 7.48 = 26.45993813 gallons
--------------------------------
answer to the nearest 100th of a gallon is 26.46 gallons.
