Answer:k=2.4
Step-by-step explanation:
Short Answer x = 1
There is nothing with the way the equation was solved. All the rules of logs were obeyed.
The problem is in the answer. Try putting log - 8 into your calculator. Do it like this if you are uncertain.
log
8
+/-
=
My calculator gives Error 2.
Rule values less than and including 0 do not have a logarithm..

V=(4/3)(pi)r^3
r=7.5
V=(4/3)(pi)(7.5^3)
V=(4/3)(pi)(7.5^3)
V=(4/3)(pi)(421.875)
V=562.5pi ft^2
if you watnt to you can aprox pi=3.14
V=562.5*3.14
V=1766.25 ft^3
so answer is 562.5pi ft^3 or 1766.25 ft^3
Scale Factor is just being multiplied to the width and length.
