here's ur answer frnd!!!
circumference of the base of cylinder=44cm
2πr=44cm
2×22/7×r=44cm
44/7×r=44cm
r=44/1×7/44
r=7cm
volume of cylinder=2310cm²
πr²h=2310cm³
22/7×7×7×h=2310cm³
22×7×h=2310cm³
154×h=2310cm³
h=2310/154
h=15cm
therefore CSA=2πrh
=2×22/7×7×15
=44×15
=660cm²
hence, 1 one is right.
hope this helps...
if it helps u plz follow me
