Answer 2

Required Answer :

• The volume of a right circular solid cylinder = 12320 cm³
• The total surface area of the right circular cylinder = 2992 cm²

Explanation :

We have,

• Radius = 14 cm
• Height = 20 cm

To find,

• The volume and total surface area of a right circular solid cylinder

Solution,

Formula to calculate the volume of a right circular solid cylinder :-

• Volume = πr²h

where,

• Take π = 22/7
• r = radius
• h = height

Substituting the given values :-

⟶ Volume = 22/7 × 14 × 14 × 20

⟶ Volume = 22 × 2 × 14 × 20

⟶ Volume = 12320

Therefore, the volume of a right circular solid cylinder = 12320 cm³

Formula to calculate the total surface area of the right circular cylinder :-

• Total surface area = 2πr(h + r)

Substituting the given values :-

⟶ Total surface area = 2 × 22/7 × 14(14 + 20)

⟶ Total surface area = 2 × 22 × 2(34)

⟶ Total surface area = 2992

Therefore, the total surface area of the right circular cylinder = 2992 cm²
