Question

The diameter of the Sun is about 1.4 x 106 km. The diameter of the planet

Venus is about 12,000 km.

What is the approximate ratio of the diameter of the Sun to the diameter of

Venus?

A. 8.5 x 10-3

B. 8.5 x 102

c. 1.17 x 103

D. 1.17 * 102

Answer 1

D.
`Ratio = 1.17 * 10^2`

Explanation:

Given

The diameters of Sun and Venus where

`Sun = 1.4 * 10^6km`

`Venus = 12,000km`

Required

Ratio of the diameter of Sun to Venus

The ratio is calculated as thus;

`Ratio = (Sun)/(Venus)`

Substitute values for Sun and Venus

`Ratio = (1.4 * 10^6)/(12000)`

`Ratio = (1.4 * 1000000)/(12000)`

`Ratio = (1400000)/(12000)`

`Ratio = 116.666666667`

`Ratio = 117 (Approximated)`

`Ratio = 1.17 * 10^2`
