Radius =12cm
height=5cm
slant height=I=v12^2+5^2 =v169=13
Base area= πr 2 = 3.14x144 = 452.16cm2
LSA = πrl=3.14x12x13=489.84cm2
Tsa=452.16 +489.84=942 cm2
volume=1/3πr 2h=1/3x3.14x12^2.x5
=753.6cm2

answer
raius=12cm
height=5cm
slant
height=l=v12^2±5^2=v169=1
base area=n rl=3.14×144=452.16cmsqure
therefore
answer is=755.6cmsqure
