1. Based on the information given in the problem above, you can calculate the surface area of a cone by using the formula:
[tex] S.A. = 3.14r^{2}+3.14rl [/tex]
2. The term [tex] 3.24r^{2} [/tex] represents the area of the base of the cone, which is a circle.
3. The other term [tex] 3.14rl [/tex] represents the lateral surface area of the cone, where [tex] l [/tex] is the slant heigth:
Therefore the answer is: [tex] 3.14r^{2} [/tex] is the area of the base of the cone and [tex] 3.24rl [/tex] is the lateral surface area of the cone.
