Answer:  [tex]656.26\ cm^2[/tex]

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 :-

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

For r=19 and l=11 , we have

[tex]L.S.A.=\pi (19)(11)\\\\\Rightarrow\L.S.A.=(3.14)(201)=656.26\ cm^2[/tex]

Hence, the lateral surface area of cone is [tex]656.26\ cm^2[/tex]
