Question 510027: What are the steps to solve for h in this problem, I have been stuck on it for over an hour.
The volume of a right circular cone is given by V=1/3 ~r^2h. Approximate the value for h if ~=22/7, r=7 ft, and V=308.
I wrote it out as 308ft^3=(1/3)(22/7)(7ft^2)h
I have been trying to use the rules for solving 1st degree equations, but I am not getting close to the answer. Could you please help me by showing me the steps to get to h

Question 510697: Equation:
P=11/2n+22 (11/2n is a fraction)
Here is what I tried:
P=11/2n+22
P-22=11/2n subtract 22 from both sides
P/11 -2=2n multiply both sides by 1/11
P/22-1=n multiply both sides by 1/2
Is this correct? Thank you for the help.
