The surface area of a cone with radius r units and slant height s units is shown below:
30 points
Surface area = 3.14(rs + r2)
Part A: If r = 3 units and s = 5 units, write an expression that can be used to calculate the surface area of the cone. (4 points)
Part B: What is the surface area of the cone? Show your work. (6 points)
