The curved surface area of a cylinder is 
and the circumference of its base is 110 cm. Find the height and the volume of the cylinder.
Given,
Curved surface area of cylinder = 4400 cm2
Circumference of its base = 110 cm
2πr = 110
= r = 
Let height of cylinder = h cm
C.S.A = 4400
2πrh = 4400
= 2 × 
× 
× h = 4400
= h = 
∴ Volume of cylinder = πr2h =
