You have the formula... V = pi * R^2 * h
4752 in^3 = 3.14 * 9"^2 * h (with the numbers plugged in)
4752 in^3 = 3.14 * 81"^2 * h (with the squaring math completed)
4752 in^3 = 254.14"^2 * h (with the multiplication math completed)
4752 in^3 / 254.14"^2 * h / 254.14"^2 (showing the division from both sides to get "h" alone)
18.68" = h (the answer)
