4*pi*r = 704cm
r= 56cm
now csa = 2*pi*r*h
=2816 sq.cm

perimeter of cylinder =704
height=8cm
perimeter of cylinder=2πr
so, 2πr=704
now we should find radius:
2×22/7×r=704
44/7×r=704
r=704×7/44
r=112cm
now we can find the CSA
CSA of cylinder = 2πrh
= 2×22/7×112×8. (r=112cm,h=8cm)
=44/7×112×8
=5632sq.cm
height=8cm
perimeter of cylinder=2πr
so, 2πr=704
now we should find radius:
2×22/7×r=704
44/7×r=704
r=704×7/44
r=112cm

=44/7×112×8
