we can do it in square feet or inches
V=hpir^2




for feet
4in=1/3ft

V=(1/3)(pi)(6^2(
aprox pi=3.141592
V=37.6991 ft^3


if in inches
12ft=144 inches
144/2=72 inches

V=(4)(3.141592)(72^2)
V=65144.1 in^3


37.6991 ft^3 or 65144.1 in^3

Now if we solve that:
$1,030
Now divide by 4 because there are 4 total weeks
$1,030 / 4 weeks
Solve that:
$257.50 a week is her average.
