Vedclass · Answer

(B) Volume of $1$ sphere $= 1.76 \ cm^3$ (which has $3$ significant figures).Volume of $25$ spheres $= 25 	imes 1.76 \ cm^3 = 44.0 \ cm^3$.According to the rules of significant figures,when multiplying a measured value by an exact number (like $25$),the result should have the same number of significant figures as the measured value.Since $1.76$ has $3$ significant figures,the result must be expressed with $3$ significant figures,which is $44.0 \ cm^3$.

List-$I$ (Number)	List-$II$ (Significant figures)
$A. 1001$	$I. 3$
$B. 010.1$	$II. 4$
$C. 100.100$	$III. 5$
$D. 0.0010010$	$IV. 6$

The volume of a sphere is $1.76 \ cm^3$. The volume of $25$ such spheres,taking into account significant figures,is:
