Question

The diameter of a sphere is 6 cm. It is melted and drawn into a wire of diameter 0.2 cm. Find the length of the wire.

Answer 1

diameter of sphere = 6cm
radius =3
Vol of sphere =
Volume =
Volume = 113.04

--
Volume of cylinder =
113.04= $\pi {0.1}^{2}h$
h = $\frac{113.04}{3.14\times {0.1}^2}$ = 3600 cm
