Answer 2

Answer :

• Curved Surface area of cone is 110cm²

Given :

• Slant Height of cone = 10cm
• Diameter of cone = 7cm

To Find :

• Curved Surface area of cone

Solution :

As in the question we are given Diameter of the cone. So, Firstly we will find the radius of the cone.

• Diameter = 7cm
• Radius (R) = 7/2 cm

⟼ CSA of cone = πrl

⟼ CSA of cone = 22/7 × 7/2 × 10

⟼ CSA of cone = 22 × 5

⟼ CSA of cone = 110cm²

∴ Curved Surface area of cone is 110cm²

______________

More Formulae :

⒈Volume of a cone = (1/3)πr²h

⒉Slant height of a cone = √(r² + h²)

⒊Lateral surface area of a cone= πrl

⒋Base surface area of a cone= πr²

⒌Total surface area of a cone = πrl + πr²
