The number of significant figures in the measured value $4.700 \,m$ is the same as that in the value ....... $m$

Three measurements are made as $18.425 \, cm$,$7.21 \, cm$,and $5.0 \, cm$. The addition should be written as ........ $cm$.

The volume of a sphere is $1.76 \ cm^3$. The volume of $25$ such spheres in terms of significant figures is ...... $cm^3$.

Taking into account the significant figures,what is the value of $9.99\, m - 0.0099\, m$ (in $, m$)?

The result after adding $3.8 \times 10^{-6}$ and $4.2 \times 10^{-5}$ with due regard to significant figures is:

For the four sets of three measured physical quantities as given below,which of the following options is correct?
$(i)$ $A_{1}=24.36, B_{1}=0.0724, C_{1}=256.2$
$(ii)$ $A_{2}=24.44, B_{2}=16.082, C_{2}=240.2$
$(iii)$ $A_{3}=25.2, B_{3}=19.2812, C_{3}=236.183$
$(iv)$ $A_{4}=25, B_{4}=236.191, C_{4}=19.5$
