the radius: r^2 = 81
r =9
c = 2*pi*r
= 2 * pi * 9
= 18 *pi
Answer: 18*pi or approximately 56.62
<h2><u>Question</u>:-</h2>
The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °, what is the measurement of the fourth angle?
<h2><u>Answer</u>:-</h2>
<h3>Given:-</h3>
The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °
<h3>To Find:-</h3>
The measurement of the fourth angle.
<h2>Solution:-</h2>
By angle sum property of a quadrilateral,
Sum of all the interior angles = 360 °
So, let the fourth angle be x
85 ° + 54 ° + 96 ° + x = 360 °
235 ° + x = 360 °
x = 360 ° - 235 ° = 125 °
<h3>The measurement of the fourth angle is <u>1</u><u>2</u><u>5</u><u> </u><u>°</u>. [Answer]</h3>
Answer:
12
Step-by-step explanation:
Just add three
Well this is a more complicated question than it may seem.
The laws of probability are based on observations whose number is very large or actually as the number of observations approaches infinity.
So on the one hand, you should be concerned that you get 0/8 to land on 3.
However, 42/500 land on 3 so your ratio has improved.
It's not near 125 but it's also not 0.
If it remained at 0, you would begin to be concerned and rightly so.
Perhaps if you did 5000, you would be less concerned as the ratio improved and got closer to 1/4 of the observations.
So at this point I don't think you have enough information to determine that the spinner is unfair.
