Given:

The diameter of circular surface is 8ft and height 9 ft.

Required:

What is the lateral area of the cone?

Explanation:

We know formula for lateral area of cone

[tex]A_L=\pi r\sqrt{h^2+r^2}[/tex]

We have diameter of circular surface is 8 cm. So radius is half of it that is 4.

Now,

[tex]\begin{gathered} A_L=3.14\times4\times\sqrt{9^2+4^2} \\ A_L\approx123.7017 \end{gathered}[/tex]

Answer:

Hence, answered the question.
