Curved surface area of cylinder =3375cm²
h=35cm
2πrh=CSA
2*22/7*r*35=3375
44*5r=3375
r=3375/220
r=675/44
Volume of cylinder =πr²h
22/7*(675/44)²*35
2278125/88
25887.78cm³
h=35cm
2πrh=CSA

Hello,
we calculate the radius of the cylinder:
r=Slat/2πh=3375/2π×35=3375/70π=15.34 cm
we calculate the volume of cylinder :
V=πr²h= π×15,34²×35=235.3156π×35=25887.78 cm³
bye :-)
