Given :
CSA of a cylinder = 4400 cm²
Circumference of base of cylinder = 110 cm
To find :
Height and volume of cylinder.
Solution :
Formulas to be used :
⇒ CSA of cylinder = 2πrh
⇒ Circumference of base of cylinder = 2πr
⇒ Volume of cylinder = πr²h
Therefore,
⇒ 2πrh = 4400
⇒ h = 4400/2πr
⇒ h = 4400/110 [∵ 2πh = 110 cm]
⇒ h = 40 cm
Now,
⇒ 2πr = 110
⇒ r = 110/2π
⇒ r = 110/(2 × 22/7)
⇒ r = 110 × (7/44)
⇒ r = 35/2 cm
Therefore,
⇒ Volume of cylinder = πr²h
⇒ Volume of cylinder = 22/7 × (35/2)² × 40
⇒ Volume of cylinder = (22/7) × (1225/4) × 40
⇒ Volume of cylinder = 22/7 × 12250
⇒ Volume of cylinder = 269500/7
⇒ Volume of cylinder = 38,500 cm³
∴ Height of cylinder is 40 cm and volume of cylinder is 38,500 cm³.
