Answer 1

Answer:

Explanation:

148325.5 km

Step-by-step explanation:

d of earth = 1275600 km

d of planet = 5/43 * 1275600 = 5 * 29665.1 = 148325.5

D of planet = 148325.5 km

Answer 2

Diameter of Earth = 12756000 m

Diameter of a new planet = 5/86 x 12756000 m = 741627.90 m

i.e., 741627.90/1000 km = 741.6 km
