A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. So, a decimal number will always round to a decimal number.
For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.

There can only be one digit in each place value - before or after the decimal place.
The normal convention when rounding numbers if to "round up" if the last decimal place is 5 or more or "round down if it is 4 or less eg. 5.55 would become 5.6 and 5.54 would become 5.5 3.999 includes 3 decimal places (the numbers after the "."), each of which would round up - so when rounded up to one decimal place it would become 4.0
5 is in the thousands position. the 3 to the left is in hundreds. the 6 is in the tens position. the second 3 is in the units position. the 4 is in the tenths position
The correct answer is 1.36
The answer depends on the situation. You could round the answer so that it does not have more significant figures than any of the components which went into calculating it.
