Question 763125
You want to calculate the result of {{{(4/3)*pi*16^3}}}.
The "4" in the {{{4/3}}} is a factor in the numerator.  The "3" in the {{{4/3}}} is a factor in the denominator.  The factors in the denominator are DIVISORS. 


Explain what you mean when you say, "sphere...is 35 feet high...".  Do you mean the distance from the sphere to the ground is 35 feet?  Or do you mean it is filled with water to a level of 35 feet?  If the first one, then your use of the formula is correct, since how high from the ground is the sphere makes no difference.
