$656.26\ cm^2$

Step-by-step explanation:

Given: The radius of the cone (r)= 19 cm

The slant height of cone (l)= 11 cm

The lateral surface area of cone is given by :-

$L.S.A.=\pi rl$ , where r is the radius and l is the slant height of the cone.

For r=19 and l=11 , we have

$L.S.A.=\pi (19)(11)\\\\\Rightarrow\L.S.A.=(3.14)(201)=656.26\ cm^2$

Hence, the lateral surface area of cone is $656.26\ cm^2$
