1. What is the surface area of the cone?

Answer:
A ≈ 297.33
Step-by-step explanation:
[tex]radius=5[/tex]
[tex]height=13[/tex]
Using the formulas:
[tex]A=\pi rl+\pi r^2[/tex]
[tex]l=\sqrt{r^2+h^2}[/tex]
Solving for A:
[tex]A=\pi r(r+\sqrt{h^2+r^2})=\pi *5*(5+\sqrt{13^2+5^2})[/tex] ≈ [tex]297.32643[/tex]
Therefore, the surface area of the cone is 297.33.
