Question

How would you round the number held in the variable pi to 3.14?

Answer 1

To round the number held in the variable pi to 3.14, follow the rules for rounding off in mathematics.

Step-by-step explanation:

To round the number held in the variable pi to 3.14, you can follow the rules for rounding off in mathematics. Since 3.14 has two decimal places, we need to round the number pi to two decimal places. Here's how you can do it:

1. Identify the digit that follows the second decimal place. In this case, it's the digit 1.
2. If the digit after the second decimal place is less than 5, you just keep the second decimal place and remove all the remaining digits. So, in this case, the rounded number would be 3.14.
3. If the digit after the second decimal place is 5 or greater, you add 1 to the second decimal place and remove all the remaining digits. For example, if the digit after the second decimal place were 6, the rounded number would be 3.15.

Since the digit after the second decimal place in pi is 5, we add 1 to the second decimal place and remove all the remaining digits, giving us the rounded number 3.14.
