Answer 1

`\sf \huge{\boxed{\sf area = 653.1 cm^2}}`

Step-by-step explanation:

`\sf \boxed{\sf area \ of \ cone=\pi r^2 +\pi rl }`

Given:

• radius: 8 m

• slant height: 18 m

using this formula:

`\hookrightarrow \sf \pi r^2 + \pi rl`

`\hookrightarrow \sf (3.14)(8)^2 +(3.14)(8)(18)`

`\hookrightarrow \sf 653.1 cm^2`
