hiii!!!
here's ur answer...
radius of the cylinder is 5cm
CSA of the cylinder=660cm²
therefore 2πrh=660cm²
→2×22/7×5×h=660cm²
→220/7×h=660cm²
→h=660/1×7/220
→h=3×7
→h=21cm
★ verification ★
CSA of the cylinder=2πrh
=2×22/7×5×21
=220×3
=660cm²
hence verified
thus the height of the cylinder is 21cm.
hope this helps..!
