Answer 2

Answer:

diameter of sphere = 6 cm

radius = 6/2 = 3cm = 30 mm

diameter of wire = 2 cm

radius = 1 mm

volume of sphere = volume of wire

4/3×π×r³ = πr²h

4/3 × r³ = r²h

4/3 × (30)³ = (1)²h

4/3 × 30 × 900 = h

4 × 10 × 900 = h

h = 36000 mm

1 cm = 10 mm

h = 3600 cm

length of wire = 3600 cm
