Marks: +1, -0

A sphere of radius 15 cm made of tin is drawn into a long wire of diameter 2 cm. What will be the length of the wire?

Solution:

(2) Let the length of the wire be hm. Since all the material of sphereis drawn into wire, total volume willremain the same. So,

4/3π×(15)^3=π×[2/2]^2×h

⇒

h =4/3× 15^3= 4500 cm
