1 Spherical water tank contains $V = \pi h^2 \frac{(3R-h)}{3}$ amount (volume) of water when the depth of the water is given with h. By using $V = 22$ and $R = 7$ calculate the depth h for the corresponding V via Newton-Raphson method with 5 iterations. Use initial value of $h_0 = 7/22$. Write down your answers into the table below with 6 significant digits. i 0 1 2 3 4 5 $h_i$ 7/22
