Answer 1

7.5

Answer 2

How did you know?

Answer 3

The surface area of a cone is just the base area plus the lateral area
The base area is 3 and the lateral area is 1.5 times as much,that is, the lateral area is 4.5
add the 3 and 4.5 for the base and lateral area respectively, we get 7.5 as the surface area.
