Answer:
given radius =5cm
height =12CM
Therefore l^2=h^2+r^2
l^2= 12^2+ 5^2
l^2=144+25
l^2=166
l=√166
l=12.8
curved surface area =πrl
22/7×5×12.8
22/7×5×128/10
11×128/7
1408/7cm2
total surface area =πr(r+h)
22/7×5(5+12.8)
22/7 ×5(5+128/10)
110/7(50+128/10)
110/7×178/10
11×178/7
=1958cm2
you missed one word that is right circular cylinder cone
