Question

A copper sphere of radius 3 cm is beaten and drawn into a wire of diameter 0.2 cm

Answer 1

Answer:

Length of Copper Wire is 3600 cm.

Step-by-step explanation:

Given: radius of copper sphere, r = 3 cm

          diameter of copper wire , d = 0.2 cm

To find: Length of wire, h

Radius of wire, R = 0.1 cm'

Volume of copper wire = Volume of copper sphere

$\pi R^2h=\frac{4}{3}\pi r^3$

$(0.1)^2h=\frac{4}{3}(3)^3$

$h=\frac{4\times9}{0.01}$

$h=3600$

therefore, Length of Copper Wire is 3600 cm.

Answer 2

Answer:

h= 3600 hope it helps you
