l^2 = r^2+h^2
l^2 = 12^2+26^2
l^2 = 144+676
l^2 = 820 cm
l= √820
l = 28.64 cm
C.S.A of cone = pi multiply r multiply l
= 3.14 multiply 12 multiply 28.64
= 1079.1552 cm^2
Volume of cone = 1/3 pi r ^2 h
= 1 /3 multiply 3.14 multiply 12^2 multiply 26
= 3918.72
l^2 = 12^2+26^2
l^2 = 144+676
l^2 = 820 cm
l= √820
l = 28.64 cm
C.S.A of cone = pi multiply r multiply l
= 3.14 multiply 12 multiply 28.64
= 1079.1552 cm^2
Volume of cone = 1/3 pi r ^2 h
= 1 /3 multiply 3.14 multiply 12^2 multiply 26
= 3918.72
