Please help me with the matlab

Q.3. In designing a spherical tank whose schematic is shown below, you need to determine the tank when the radius R of the tank is 3 m, and the volume V is 35 m3The equation for computing V as a function of R and h is: the height of water in 2 13R - h Treat this is an f(h) Oproblem to compute the height of water in the tank for the given values of V and R (a) Use fplot directly to generate a plot of the variation of f(h) against h in a range that helps locate the approximate root. (b) Use fzero directly with the aid of the approximate root from (a) to compute the desired root accurately
