Integers are irrational numbers. A natural number is a rational number. An irrational number is a real number. Zero is a natural number.

This question is about compound interest, but since the interest is such a small number you can use what you know about simple interest to eliminate some answers.
You can immediately eliminate choice A as a clunker, since it is less than the original amount in the account.
Consider what the amount of interest would be if you make the rate much larger than the original rate, say 10%, or 0.1:
$6,500 × 0.1 = $650
If this amount were added to the original amount each year for two years, the total would be:
$6,500 + $650 + $650 = $6,500 + $1,300 = $7,800
This is an over-estimate for the information given, and since choices C and D are even greater than this over-estimate, they can be eliminated. That means choice B is the correct answer.
Answer:
0.96
Step-by-step explanation:
The formula for this is
. If the diameter is 8 the radius is 4, so filling in accordingly we have
and
which is
and when you multiply in 3.14 you get that A = 401.92 or B above.
