Answer:
0.01 cm, If I am not wrong.
Step By Step Explanation:
Let h1 be the height of solid cylinder and r1 be its radius and r2 is the radius of wire(cylinder shaped) and h2 is its height or length.
Given that:
H = 1 cm R = 1 cm r = 0.1 cm
Here we have to equal the volumes as the same material is recasted into another shape.
