Answer:
height of the cylinder= 20cm.
Step-by-step explanation:
curved surface area of the cylinder=2πrh.
radius of the cylinder=14cm.
2πrh=1760cm^2.
2*22/7*14*h=1760cm^2.
therefore, height of the cylinder=1760*7/2/22/14
=20cm.

Answer:
2(π)rh=1760
2∗22/7∗210∗h=1760
2∗22∗30∗h=1760
h=1760/(44∗30)
h=176/132
h=44/33=4/3cm
