A square sheet of side length 44 cm is rolled along one of its sides to form a cylinder by making opposite edges just to touch each other. What is the volume of the cylinder? (Take π = 22/7)
Elementary MathematicsMensuration
- A6776 cubic cm
- B6248 cubic cm
- C5896 cubic cm
- D5680 cubic cm
Explanation
Rolling the sheet makes its side the circumference: 2πr = 44 gives r = 7 cm, with height 44 cm. The cylinder's volume is (22/7) × 49 × 44 = 6776 cubic cm (A).
