Step-by-step explanation:
Area of a curved surface of a cylinder = 4400 cm².
The circumference of its base = 110 cm.
As we know that,
Formula of : circumference of base = 2πr.
→ 2πr = 110.
→ πr = 55.
Formula of : Curved surface area of cylinder = 2πrh.
→ 2πrh = 4400.
Put the value of πr = 55 in the equation, we get.
→ 2(55)h = 4400.
→ 110h = 4400.
→ h = 40 cm.
Height of cylinder = 40 cm.
