Answer:
12.56 ft.
Step-by-step explanation:
The formula of the circumference is
C = pi *d where d is the diameter
C = 3.14 *4
C =12.56
Answer:

Step-by-step explanation:
Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.
You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached. As you can see:

And we can find a easily using pythagorean theorem:

Solving for a:


Therefore:

They are not congruent because they are the same shape just flipped around
Answer:
There is 0.1538 or 15.38% probability that the next person Rona sees will be wearing boots.
Step-by-step explanation:
Total number of People = 13
People wearing boot = 2
Experimental Probability = Number of times event occurs / Total Number of Trials
Experimental Probability = 2 / 13
Experimental Probability = 0.1538
Or
Experimental Probability = 15.38%
So, there is 0.1538 or 15.38% probability that the next person Rona sees will be wearing boots.
That would be B
|-6| + |4| = 6 + 4 = 10
