Answer:
[tex]\sf \huge{\boxed{\sf area = 653.1 cm^2}}[/tex]
Explanation:
[tex]\sf \boxed{\sf area \ of \ cone=\pi r^2 +\pi rl }[/tex]
Given:
using this formula:
[tex]\hookrightarrow \sf \pi r^2 + \pi rl[/tex]
[tex]\hookrightarrow \sf (3.14)(8)^2 +(3.14)(8)(18)[/tex]
[tex]\hookrightarrow \sf 653.1 cm^2[/tex]
