Answer:
(i) The radius of the scale model of the Earth is 12.7 cm and its volume is 8580.25 cm³ (ii)
Step-by-step explanation:
First you have to find the ratio between the radius of the Moon and the radius of its model (3.4 cm/1700km) and then multiply it for the radius of the Earth model.
Radius of the scale model of the Earth = 6350 km x (3.4 cm/1700 km)
⇒Radius of the scale model of the Earth = 12.7 cm.
Finally, to find the volume of the scale model of the Earth you have to use the formula for the volume of a sphere.
V= 4πr³/3 ⇒ V= 4π(12.7 cm)³/3⇒ V= 8580.25 cm³
