Curved surface area of cylinder is 2πrh
r = 10.5 cm
CSA = 1320
2 x 22/7 x 10.5 x h = 1320
h = (1320 * 7) / (2 * 10.5 * 22) = 20
h = 20

no aapka answer glat ha
ab check kar lo
He missed to divide it by 22
yep i missed that but then edited now

Given,
radius, r = 10.5 cm
Let height be h
Then, curved surface area
2πrh = 1320
h = 1320/(2×π×10.5) = 20 cm
radius, r = 10.5 cm
Let height be h
Then, curved surface area
2πrh = 1320
h = 1320/(2×π×10.5) = 20 cm
