Use the formula 2pi×r×h
H will be 12
R will be 6
That means
csa=2×3.14×6×12
=452.16 :))))

Hey.....!!!
________________
Side of square = Height of cylinder and diameter of cylinder = 12cm
Therefore , height of cylinder = 12cm
Radius = 6cm
C .S . A of cylinder = 2πrh
= 2 x 22/7 x 6 x 12
= 3168/7
= 452.571 cm ²
