Q9 of 62 Page 22

The curved surface area of a cylinder is 1320 cm2 and its base has diameter 21 cm. Find the height of the cylinder.

Given,


Curved surface area of cylinder = 1320 cm2


Diameter of base = 21 cm


Radius of cylinder =


Let height of cylinder = h cm


So,


=


=


Height of cylinder = 20 cm
