Question

The moon has a circumference of about 10,920,000 meters. Give the circumference of the moon in scientific notation

Answer 1

The circumference of the moon in scientific notation is around
`1.092 * 10^(7)` m.

Explanation:

The moon has a circumference of about 10920000 meters. We need to express this value using scientific notation.

Scientific notation usually finds a number between 0 and 10, and this number is multiplied by 10, 100, 1000 and so on.

The number between 0 and 10 should be 1.092. Now we need to find an adequate exponent of 10.

The original value
`10920000.00 = 1.092 * 10^(7)` has the decimal part after seven places of the number 1. It means our number between 0 and 10 should be multiplied by ten seven times. it means
`10^(7)`.

Finally, we can conclude that the circumference of the moon in scientific notation is around
`1.092 * 10^(7)` m.

Answer 2

`1.092*10^(7)\ m`

Explanation:

we know that

`10,920,000\ m=(1.092)*10,000,000\ m`

`10,000,000=10^(7)`

substitute

`10,920,000\ m=1.092*10^(7)\ m`
