TSA of a cylinder = 2 pi r ( r + h )
= 2 × 22/7 × 7 (7+21)
= 2 × 22 × 28
= 44× 28
= 1232m^2
hope it helps... :)
plz mark me as brainliest if it helps u... ;))

TSA of cylinder = 2€r (r+h) Assume €=pie
=2*22/7*7 (7+21)
=2*22/7*49+147
=2*22*7+147=44*154
=6776m
=2*22/7*7 (7+21)
=2*22/7*49+147
=2*22*7+147=44*154
=6776m
