Answer:
Radius = 7 m
Height = 3 m
Slant height= root(7^2 - 3^2 )
= root (49-9)
= root40 = 2 root10 m
TSA of cylinder = pi × r × l + pi × r^2
= pi × r (l + r)
= 22/7 × 7(2 root10 + 7)
= 22(2 root10 + 7)
= 44 root10 + 154
= 293.14 m^2

TSA of cylinder = pi × r × l + pi × r^2
= pi × r (l + r)
= 22/7 × 7(2 root10 + 7)
= 22(2 root10 + 7)
