423.9 m^2 is the required lateral surface area of the cone.

Step-by-step explanation:

The lateral surface area of cone is:

$\pi\cdot r\sqrt{h^2+r^2}$

Slant height is l which is $l=\sqrt{h^2+r^2}$

We have given diameter 18 m

Since, radius is half of diameter so r=18/2 =9

Slant height l =15

$\pi=3.14$

On substituting the values in the formula we get:

$3.14\cdot 9\cdot 15$

On simplification we get:

$3.14\cdot 135$

Further simplification will give:

423.9 m^2 is the required lateral surface area of the cone.
