Answer:
18.85 mm.
7.73 mm^2.
Step-by-step explanation:
The side of the square = sqrt 36 = 6 mm.
Now this side = the diameter of the circle.
So the circumference of the circle = π * 6 = 18.85 mm.
The answer to the second part
= area of the square - area of the circle
= 36 - π *3^2
= 36 - 28.27
= 7.73 mm^2.
Answer:
4
Step-by-step explanation:
He should add 4 black blocks because there are a total of 4 other blocks, and in order to have a probability of 50%, the number of black blocks needs to be equal to the total number of the other colored blocks.
50,000 is 45,122 rounded to the nearest ten thousands

Answer: Comelia is correct</h3>
====================================================
Explanation:
We're told that "Christopher says that all Rational (Q) numbers are Whole (W)", which makes Christopher not correct. Some rational numbers are whole numbers. For instance, the number 7 = 7/1 is rational and it's a whole number as well.
However something like 1/2 is rational, but it's not a whole number. A whole number doesn't have any fractional or decimal part to it. It can be thought of the number of something.
Comelia is correct because all whole numbers are rational. If x is some whole number, then x = x/1 is rational as well. Replace x with any whole number you want. Her statement does not work in reverse as shown above.
When drawing a Venn diagram, the circle for "whole numbers" will be entirely inside the circle for "rational numbers", and not the other way around.
