Question

the curved surface of a right circular cylinder is 1760cm2 and it's radius is 14 cm. find its length
​

Answer 1

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

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
