radius=10.5cm
curved surface area=1320cm^2
2×22/7×10.5×h=1320
h=20 cm
Hope it helps!!

"The curved surface are of a cylinder = 1320 square cm
Base radius of a cylinder = 10.5 cm
Let the height of the cylinder be h
Hence, Curved Surface Area = 2 * pi * r * h
1320 = 2 * 22/7 * 10.5 * h
1320 = 2 * 22/7 * 21/2 * h
1320 = 22 * 3 * h
1320/66 = h
H= 20 cm
