Question

A rectangular paper of width 14 cm is rolled along its width and a cylinder of radius 20 cm is formed. The volume of cylinder will be:
1. 17,600 cm³
2. 18,600 cm³
3. 18,593 cm³
4. 19,600 cm³

Answer 1

Correct Answer - Option 1 : 17,600 cm³

Given:

The width of the rectangular = 14 cm

Formula used:

The volume of the cylinder = π × r² × h  (Where, r = The radius of the cylinder and h = The height of the cylinder)

Calculation:

Let be assume the height of the cylinder is h and the radius is r.

⇒ The height of the cylinder = Width of the rectangular paper

⇒ h = 14 cm, r = 20 cm

⇒ The volume of the cylinder = (22/7) × 20² × 14 = (22 × 400 × 2) = 17600 cm³

∴ The required result will be 17600 cm³.
