heya frnd!
here's ur answer...
circumference of the base of cylinder=252cm
→2πr=252cm
→2×22/7×r=252cm
→44/7×r=252cm
→r=252/1×7/44
→r=1764/44cm
given height of the cylinder is 3m
we know that 1m=100cm
therefore 3 metres=3×100
=300m
CSA (lateral surface area) of the cylinder=2πrh
=2×22/7×1764/44×300
=2×252/2×300
=2×126×300
=75600cm²
in metres=75600/100
=756m²
hope this helps u..!
