I need help with finding the domain of the r value.
I have
rE(0, ?]
How would I find the largest r value? I know that the largest value occurs when h is the smallest. The height.. could it be 0? But then this doesn't make sense:
V=500
500=pi r ^2 h
so if h = 0 then it cancels out r, and I can't find the largest value of r.
Please help me find the domain of the r value. Thanks
