  1. In the case of the cone, base area is PIr^2

    Surface area of a cone is area base+area cone= PIr^2+PI*radius*slantheight

    so you will need slant height to solve.

    Jodi says that if you double the radius of a right circular cone and divide the slant height by 2, then the surface area of the cone stays the same since the 2s cancel each other out. How do you respond?
