Question

Find the Surface Area of the cone.

Answer 1

Answer:

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

Explanation:

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

Given:

• radius: 8 m

• slant height: 18 m

using this formula:

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

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

$\hookrightarrow \sf 653.1 cm^2$
