Question

The volume of a sphere is $1.76{\mathrm{cm}}^3$. The volume of $25$ such spheres taking into account the significant figures is

• A. $0.44\times {10}^2\mathrm{cu}.\mathrm{cm}$
• B. $44.00\mathrm{cu}.\mathrm{cm}$
• C. $44.0\mathrm{cu}.\mathrm{cm}$
• D. $44\mathrm{cu}.\mathrm{cm}$

Answer 1

The correct option is C

$44.0\mathrm{cu}.\mathrm{cm}$

Explanation for the correct option:

The volume of a sphere $=1.76{\mathrm{cm}}^3$

The volume of $25$ such sphere is,

$$\begin{gathered} V=1.76\times 25 \\ =44{\mathrm{cm}}^3 \end{gathered}$$

Volume of sphere in the significant figures is represented as $44.0\mathrm{cu}.\mathrm{cm}$ because the given volume is in three significant figures.

Hence, the correct option is (C).
