Answer :
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]
I did the test got 100% and the answer are
1. 448 cm^2
2. 209 pi cm^2
3. 351 m^2
4. 240 cm^2
5. 561.1 pi cm^2
hope this helps :)
