Reil [10]

Answer:

1) 12.7 cm

2) 8580.24 cm³

Step-by-step explanation:

given,

Radius of moon(Rm) = 1700 Km Radius of Earth(Re) = 6350 km

Model radius of Moon(Mm) = 3.4 cm

2) Volume of earth model = $\dfrac{(R_e)^3}{(R_m)^3}\times \dfrac{4}{3}\pi (M_m)^3$

= $\dfrac{(6350)^3}{(1700)^3}\times \dfrac{4}{3}\pi (3.4)^3$

= 8580.24 cm³

1) radius of earth = $\dfrac{R_e}{R_m}\times M_m$

= $\dfrac{6350}{1700}\times 3.4$

= 12.7 cm
