Question

If the curved surface area of a cylinder is 1760cm^2 and its base radius is 14 cm.then find its height

Answer 1

Answer:

Given,

CSA of the cylinder = 1760 cm²

Base radius = 14 cm

We know that the CSA of a right circular cylinder is given by = 2πrh

CSA = 2 x 22/7 x 14 x h

1760 = 2 x 22 x 2 x h

20 = h

Hence, the height of the cylinder was 20 cm.

Hope it helps you......

Answer 2

Answer:

height =20 cm

Given =》

Curved surface area =1760 cm²

Radius =14cm

To find:-

height =?

Solution =》

Curved surface area of cylinder =2 pi r h

$1760 = 2 \times \frac{22}{7} \times 14 \times h \\ = \frac{1760 \times 7}{2 \times 22 \times 14} = h \\ = h = 20cm$

hope IT HELPs....
