Question 228773
v=pi*R^2h solve for h my answer i came up with was v/3.14*R^2=h 
h = V/(pi*r^2), which is what you got.
Notice it's pi, the Greek letter, not pie, the dessert.
------------------------------------
i=e+v/r solve for v
If it's i = (e+v)/r, then
v = ir - e
------------
If it's i = e+(v/r), then
v = (i - e)*r
-----------------------
i came up with r*i*e=v im just wondering if im correct because i dont feel 100 percent certain i am correct
