Answer:
C
Step-by-step explanation:
This has to be C because you need to divide pi from r squared bc they r multiplied. Then you get a/pi = r squared. You need to find the square root of a/pi. So r equals square root a/pi.
If the 4 states have to be in a specific order say ABCD,
then the total number of different possible routes is:
43P4 = 2,961,840
So the probability is:
1 / 2,961,840 = 3.38 x 10^-7
But if the 4 states can be in any order such as DBAC,
ACBD etc, then the total number of different possible routes is:
43C4 = 123,410
So the probability is:
1 / 123,410 = 8.1 x 10^-6
No I don’t think it is practical to list all the
different possible routes to select the one that is best. We can simply use
mathematical models to solve for that one.

Answer:
Step-by-step explanation:
r = 7 cm
h = 15cm
pi = 3.14
Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).
Area = 2* pi *r^2 = 2 * 3.14 * 7^2
Area = 2 * 3.14 * 49
Area = 307.72 Don't round this.
Cylinder body
Cylinder body = Circumference * h = 2*pi * r * h
Cylinder body = 2* 3.14 * 7 * 15
Cylinder body = <u> 659.4</u>

Answer:
The area of the circle with a 3-inch diameter is 7.07 square inches.
Step-by-step explanation:
The formula for the area of a circle is
A = πr²
If you are given diameter, take half of that to get the radius: 3 ÷ 2 = 1.5
Then take the radius, 1.5 and square it (multiply by itself) 1.5 × 1.5 = 2.25
Then multiply r² times pi. You can use 3.14. (sometimes you will need 3.14159)
2.25 × 3.14 = 7.065
Your instructions are to "round to the nearest hundredth" so you look to the thousandth place and see a 5. Rules fro rounding: "If the number is 5 or higher, add 1 to the place you are rounding to. If 4 or less, leave the place as it is."
You see a 6 in the hundredths place. Add 1. so the rounded answer is 7.07.
Then you put in the units measure. Inches are given, so the Area will be square inches
7.07 in²
