Answer 1

Answer:

The radius of the cylindrical shape wire is 6cm

Step-by-step explanation:

Let , 'h' be the height of the cone in cm

By using Pythagoras theorem,

:.slant height (l)² = (h)² + (r)²

:. (41)² = h² + (9)²

:. 1681 = h² + 81

:. h² = 1681 – 81

:. h² = 1600

:. h = 40 cm ---( by taking square root )

Let , 'R' be the radius of cylindrical wire and

'H' be the height of cylindrical wire in cm

Here,

The volume of cone and cylinder are same

:. 1/3 × π r² h = π R² H

:. 1/3 × (9)² × 40 = R² × 30

:. 1/3 × 81 × 40 = R² × 30

:. 27 × 40 = R² × 30

:. 1080 = R² × 30

:. R² = 1080 / 30

:. R² = 36

:. R = 6 cm

:. The radius of cylindrical wire is 6 cm
