Question

In order to maintain the same vol, by what factor should the length of the wire be

increased if the radius is decreased by 5 times. Give the answer in a statement
​

Answer 1

Step-by-step explanation:

volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.

Answer 2

Answer:

$volume = kr {}^{2} l \\ where \: k = constant \: \\ r = radius \\ l = length$

Now if radius is reduced to 1/5 of r then

$r {}^{2} reduces \: to \: \frac{1}{25}$

means length has to be increased by 25 times.
