I need step by step solution Iam stuck Iam using math lab and need appropriate formula to use to solve this problem please I need your help

[3 points) The volume v and paper surface area A of a conical paper cup are given by h and A Where r is the radius of the base of the cone and h is the height of the cone. a) By eliminating h, obtain the expression for A as a function of r and v.create a user-defined b) function that accepts r as the only argument and computes A for a given of v. For V 10 in 3, use the fminbnd function to compute the value of r that minimizes the area A What is the corresponding value of the height h? cation A ar ea r) un
