hello frnd!
here's ur answer...
circumference of the base of cylinder=220cm
therefore 2πr=220cm
2×22/7×r=220cm
44/7×r=220cm
r=220/1×7/44
r=5×7
r=35cm
radius of the cylinder is 35cm
given height is 2m means 200cm
CSA of the cylinder=2πrh
=2×22/7×35×200
=44×5×200
=44×1000
=44000cm²
in metres=44000/100
=440m²
hope this helps...
