curved surface area of the cylinder is 4400 cm sq the circumference of its base is 110 cm . find the heoght of the cylinder ??
Let the radius of base and height of the cylinder be r and h respectively.
Given: Circumference of base = 110 cm
⇒ 2πr = 110 cm ...(i)
and Curved surface area = 4400 cm2
⇒ 2πrh = 4400 cm2
⇒ 110 cm × h = 4400 cm2
⇒ h = 4400/110 = 40 cm
Hence, required height of the cylinder is 40 cm
