<PRE><B>Question 156475</B>
from the internet it was determined that 7.48 gallons of water equals 1 cubic foot in volume.

this translates to .13368984... cubic feet per gallon of water.

you have 50000 gallons of water so the volume would be 50000 * .13368984... = 6684.49491979... cubic feet.

to put it in a sphere you then take the formula for the volume of a sphere and works backwards to get the radius of the sphere.

formula for volume of a sphere is 4/3 * pi * r^3.

formula becomes volume = 6684.4949... cubic feet = 4/3 * pi * r^3

becomes r^3 = 6684.4949 ... / ( 4/3 * pi )

becomes r^3 = 1595.804911 cubic feet.

becomes r =  cube root of 1595.804911

becomes r = 11.6858... feet.

pi is a constant with value of 3.141592654...

radius is 11.6858... feet.
