Question

3.9(5π/3)
Please give an explanation on how to do this. Thank you!

Answer 1

Answer:
`(19.5\pi )/(3)\approx20.42`

Explanation:

I assume that you need to find the product.

It is known that a fraction has the following form:

`(a)/(b)`

Where "a" is the numerator and "b" is the denominator.

For this exercise it is important to remember that:

`(a)((b)/(c))=(ab)/(c)`

In this case you have the following expression given in the exercise:

`3.9((5\pi )/(3))`

You can observe in the expression that the numeartor of the fraction is
`5\pi`, and the denominator is
`3`

So, in order to find the product, you need to multiply the numerator (which is
`5\pi`) by the decimal number located outside of the parentheses (which is
`3.9`), and then you must divide that result by the denominator.

Through this procedure, you get the following result:

`3.9((5\pi )/(3))=((5\pi)(3.9))/(3)=(19.5\pi )/(3)\approx20.42`
