Given

Volume of Right Circular Cone = 1100cm³

Radius of base = 5cm

To Find

Curve surface area

Formula we use

Volume of Cone =1/3πr²h

Curve surface area = πrh

Where , r = Radius of Base , h = Height of cone

Now unknown value is Height of cone we get height of cone from volume formula

1100cm³ = 1/3π(5cm)²h

1100cm³ × 3 = π × 25cm² × h

3300cm³ = π × 25cm² × h

3300cm³ / 25cm² = π×h

132cm/π = h

Now we get value of h so we Easily Find curve surface area

Curve surface area = πrh

Curve surface area = π×5cm×132cm/π
Curve surface area = 5cm × 132cm
Curve surface area = 660cm²

Answer

• Curve surface area = 660cm²
