A piece of paper has a
Allisa [31]

Answer:

The volume of the resulting cylinder is 385 cm³

Step-by-step explanation:

The formula of the rule of a cylinder is V = π r² h, where

  • r is the radius of its base
  • h is the height of it

<em>When a rectangular paper folded to form a cylinder, then one of its dimension will be the circumference of the base and the other dimension will be the height of the resulted cylinder</em>

∵ ABCD is a rectangle

∵ It is folded where AB coincides with DC

∴ AB is the height of the resulted cylinder

∴ BC is the circumference of the base of the resulted cylinder

∵ AB = 10 cm

∴ h = 10 cm

∵ BC = 22 cm

∴ The circumfrence  of the base = 22 cm

∵ The circumference of a circle = 2 π r

→ Equate the rule by 22 to find r

∴ 2 π r = 22

∵ π = \frac{22}{7}

∴ 2 × \frac{22}{7} × r = 22

∴ \frac{44}{7} r = 22

→ Divide both sides by \frac{44}{7}

∴ r = 3.5 cm

→ Use the formula of the volume above to find the volume of the cylinder

∵ V = \frac{22}{7} × (3.5)² × (10)

∴ V = 385 cm³

∴ The volume of the resulted cylinder is 385 cm³
