What’s the circumference of a circle with a diameter of 9 inches? Use 13.14 for n

Answer:
The circumference of the circle is 28.26 inches.
Step-by-step explanation:
If you think about it in retrospect, circles must have been hard to find the perimeter of in the old math days. They weren't straight like squares, so it must have been really hard to approximate what the perimeter would have been for a circle.
Luckily, these days, we don't have to worry about that anymore. Now we know that the perimeter of a circle, also known as the circumference, can be found with the following formula:
where is a constant;
and d is the diameter of a circle.
The diameter of a circle, in my own words, is the length of a line that intersects the center of the circle as well as two points on that circle. Half of the diameter is also known as the radius.
Luckily, for this problem, we're already given and the diameter <em>d</em>, so we just have to plug them in to find the circumference.
Therefore, without rounding, the circumference of the circle is 28.26 inches.

The option which makes more sense for Jake to choose is option (1) He can accept the tie, and the game is over.
<h3>How to determine the best option to choose?</h3>The complete question is added as an attachment
From the complete question, the probability in part D is
Probability = 33.5%
The options to choose one from are:
- Option 1: He can accept the tie, and the game is over.
- Option 2: He can make one more throw. Jake wins if he earns at least 30 points on the throw, but he loses if he earns less than 30 points.
The calculated probability is less than 0.5.
This means that Jake is more likely to lose than win
So, the best option for Jake is option (A) walk away
Hence, the option which makes more sense for Jake to choose is option (1) He can accept the tie, and the game is over.

Therefore the value of
Step-by-step explanation:
Given:
m∠ A = 56°
m∠ B = 75°
m∠ ACD = x°
To Find:
x = ?
Solution:
In Δ ABC
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Here,
The opposite interior angles are angle A and angle B.
An exterior angle of a triangle is angle ACD which is x°
∴ ...Exterior angle property of Δ
Substituting the values we get
Therefore the value of
