Question
The sum of the radius and height of a cylinder is 42m.
The total surface area of the cylinder is 5544 m². What is the volume of the cylinder?Solution
Surface area of the cylinder = 5544 m². ⇒ 2 πr ( r + h ) = 5544 m² ⇒ 2 × 22/7 × r × 42 = 5544 m² ⇒ r = (5544 × 7 )/(2 × 22 × 42) = 21 ∴ h = 42 - 21 = 21m ∴Volume of the cylinder = πr² h = 22/7 × 21 ×21 × 21 = 29106 m³
