Curved surface of area:
A = 2 r π ∙ h
Divide both sides by 2 r π
A / 2 r π = h
1760 / 2 r π = h
h = 1760 / 2 r π
h = 880 / r π
Volume of area:
V = r² ∙ π ∙ h
V = r² ∙ π ∙ 880 / r π
V = r ∙ 880
880 r = V
Divide both sides by 880
r = V / 880 = 12320 / 880 = 14 cm
h = 880 / 14 π
h = 2 ∙ 440 / 2 ∙ 7 π
h = 440 / 7 π = 20,00805 cm
Approx.
h = 20 cm
The curved surface area of the cylinder is 1760cm^2and its volume is 12320cm^3 find its height

My typo.
Curved surface of cylinder:
A = 2 r π ∙ h
Volume of cylinder:
V = r² ∙ π ∙ h
Curved surface of cylinder:
A = 2 r π ∙ h
Volume of cylinder:
V = r² ∙ π ∙ h
