Answer 2

The length of wire is 5081.48 cm.

Step-by-step explanation:

Since we have given that

Radius of sphere = 7 cm

Radius of wire =0.3 cm

We need to find the length of wire,

So, Volume of sphere = volume of wire

$\dfrac{4}{3}\pi r^3=\pi r^2h\\\\\dfrac{4}{3}\pi \times 7\times 7\times 7=\pi (0.3)^2\times h\\\\\dfrac{4\times 343}{3\times 0.09}=h\\\\h=5081.48\ cm$

Hence, the length of wire is 5081.48 cm.
