Question

The diameter of copper sphere is
6 cm the sphere is melled to long
whire on
length 36 cm find the radius of
the wire​

Answer 1

Answer:

R = d/2 = 6/2 = 3

Therefore the radius is 3 cm

Answer 2

Answer:

kindly see the answer below......

Step-by-step explanation:

HERE,

according to the question...

the diameter of the copper sphere is 6 cm..

so, volume of the COPPER SPHERE is

$= \frac{4}{3} \times \pi \times {3}^{3}$

$= 113.1 \: {cm}^{3}$

Therefore, let the radius of the long wire be r cm with length 36 cm.

Now,

$113.1 = \pi \times {r}^{2} \times 36$

$or \: \: {r}^{2} = \frac{113.1}{36} \times \frac{1}{\pi}$

$or \: \: r = \sqrt{1} cm$

$or \: \: r = 1cm$

so, the radius of the wire is 1cm.

thanks a lot...
