h= 30×3 =90 cm
R = 14 cm
TSA = 2πr(h+R) = 9152cm^2
volume = πr^2h =55440 cm^3
R = 14 cm
TSA = 2πr(h+R) = 9152cm^2
volume = πr^2h =55440 cm^3

when placed one above another forms a cylindrical shape
therefore,
h=(2×30 ) cm
=60 cm
tsa=2×22/7× 14(60+14)
=22792cm^2
volume = 22/7 ×14×14×60
= 36960cm^3

h=(2×30 ) cm
