Hey mate!
Here is your answer > >
Radius of circular cylinder=2.1 cm
Circumference of cylinder=2 π r
=2×22/7×2.1
=13.2 cm
Height of cylinder=Circumference of cylinder = 13.2 cm
C.S.A of cylinder=2 π rh
=2×22/7×2.1×13.2
=174.24 cm^2
T.S.A of cylinder=2 πr (r+h)
=2×22/7×2.1(2.1+13.2)
=44×2.1×15.3/7
=201.96 cm^2
Hope it helps!
