Given:

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

Required:

What is the lateral area of the cone?

Step-by-step explanation:

We know formula for lateral area of cone

$A_L=\pi r√(h^2+r^2)$

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

Now,

$\begin{gathered} A_L=3.14*4*√(9^2+4^2) \\ A_L\approx123.7017 \end{gathered}$

Answer:

Hence, answered the question.
