Question

8. In a drawing of the solar system, the scale is 1 mm = 500 km. For a planet with a diameter of (1 point)

7,000 km, what should be the diameter of the drawing of the planet?
3,500,000 mm
140 mm
14 mm
7,000 mm

Answer 1

Answer: The diameter of the drawing of the planet= 14 mm

Explanation:

Given: In a drawing of the solar system the scale is 1 mm = 500 km

which means
`1 \ km=(1)/(500)mm` on the drawing.

The diameter of planet =7000 kilometers.

Then the diameter of the drawing of the planet
`=(7000)/(500)=14`

Therefore, the diameter of the drawing of the planet= 14 mm.
