Question

115. When a copper ball is hented, the largest
percentage increase will occur in its
ta) diameter (b) area
(c) volume (d) density.​

Answer 1

Answer:(c)

Formulas of shapes

Area = $4\pi r^2$

Volume = $\frac{4}{3} \pi r^3$

Density = (Mass) / (Volume) = (Mass) *  $\frac{3}{4\pi r^3}$

The diameter will be $k$ times bigger

Since k>1

$k^3>k^2>k>1>\frac{1}{k^3}$

The answer is (c)

Answer 2

option c

volume is the right answer
