Question

The radii of earth and Pluto are 6,371 kilometers and 1161 kilometers, respectively. Approximately how many spheres the size of Pluto does it take to have the same volume as earth

Answer 1

Answer:

165

Step-by-step explanation:

Here we have to use the ratio.

Both earth and Pluto are in similar shapes.

To find the number of sphere the size of Pluto does it take to have the same volume, we need to divide the earth's volume by Pluto's volume.

= Earth's volume/Pluto's volume

= 4/3 π (6371)^3 ÷ 4/3 π (1161)^3

Cancelling out 4/3 π both in the numerator and in the denominator, we get

= (6371)^3 ÷ (1161)^3

= 258596602811 ÷ 1564936281

= 165.24

Approximately 165 spheres the size of Pluto to cover the earth volume.

Thank you.
