Radius of earth=r
volume=4/3πr²*r
=4/3*22/7*r²*r=4.13 r ^{3}
radius  of moon= \frac{4}{3} * \pi * (\frac{r}{2} ) ^{3}  \\  \\ 
4.19*  \frac{ r^{3}}{8}
ratio(moon:earth)=1:8

surface area(earth)=2 \pi  r^{2} 
=44/7* r^{2} \\
surface area(moon)=2*22/7*( \frac{r}{2})^{2}   \\  \\ 
 \frac{44}{7} * \frac{ r^{4} }{4}
ratio(moon:earth)=1:4
