The radius of the earth is 6371 km. The radius of the planet Mars is 0.53 of the radius of the Earth. Find the radius of the planet Mars.

If the radius of the planet Mars is 0.53 parts of the radius of the Earth, and the radius of the Earth is 6371 km, then in order to determine the radius of the planet Mars, it is necessary to multiply 6371 km by 0.53.
Multiply 6371 by 0.53 “per column”
Thus, (6371 km) * 0.53 = 3376.63 km.
Now let’s round the result to tenths. Since in the number 3376.63 the decimal place is occupied by the number 3 and 3 <5, we discard this number (3) without adding 1 to the number 6 (the tenth place). Therefore, we get rounding to tenths: 3376.63 ≈ 3376.6.
The radius of the planet Mars is 3376.6 km.
Answer: The radius of the planet Mars is 3376.6 km.
