Question

How many times around the Earth is 3.7 trillion apples ?

The circumference of earth is 40,075km and a average size of an apple is approximately 8.3cm.

Show the working out step by step.

Answer 1

`7,663` times around the Earth

Explanation:

we know that

`1\ trillion=1,000,000,000,000=1*10^(12)` (one million million)

The average size of an apple is approximately 8.3 cm

Convert to km

`8.3\ cm=8.3/100,000=8.3*10^(-5)\ km`

Multiply by 3.7 trillion apples

`3.7*10^(12)*8.3*10^(-5)=30.71*10^(7)=3.071*10^(8)\ km`

Divide by the circumference of earth (40,075 km)

`3.071*10^(8)/40,075=7,663\ times`
