0:30 a. (5 pts) The formula for computing the surface area of a cone is: of the cone and / is the slant height of the lateral (side) surface. r2 + rl, where r is the radius of the base Write a step-by-step algorithm for computing the surface area of the cone. Values required are the radius, slant height, and a value for pi (in the actual code, the value for pi will be defined). The output is the area of the cone. Use plain English statements (no programming instructions required), and number your steps. You may ignore units. Lateral Surface Base
