Answer:

[tex]SA=106.46cm^2[/tex]

Step-by-step explanation:

We will have to use the formula to find the surface area of a cone, which is:

[tex]SA=\pi r(r+\sqrt{h^2+r^2})[/tex]

Dimensions of the cone:

Radius: 4cm

Height: 2cm

Plug in numbers for the variables and solve:

[tex]SA=\pi (4)(4+\sqrt{2^2+4^2})[/tex]

[tex]SA=106.46cm^2[/tex]
