Answer:
C = 40.2124
Step-by-step explanation:
The formula for circumference is
C = 2*pi*r
where r is the radius.
Substitute what we know.
C = 2 * pi * 6.4
C = 12.8 * pi
If we use substitute pi in, we get
C = 40.2124
Answer:
![(9x-5)\ units](https://tex.z-dn.net/?f=%289x-5%29%5C%20units)
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The perimeter of a triangle is the sum of the length of their three sides
so
![P=a+b+c](https://tex.z-dn.net/?f=P%3Da%2Bb%2Bc)
where
a,b,c are the length sides of the triangle
In this problem we have
![P=(16x-6)\ units\\a=(2x-5)\ units\\b=(5x+4)\ units](https://tex.z-dn.net/?f=P%3D%2816x-6%29%5C%20units%5C%5Ca%3D%282x-5%29%5C%20units%5C%5Cb%3D%285x%2B4%29%5C%20units)
substitute and solve for the missing length
![(16x-6)=(2x-5)+(5x+4)+c\\c=(16x-6)-(2x-5)-(5x+4)\\c=(9x-5)\ units](https://tex.z-dn.net/?f=%2816x-6%29%3D%282x-5%29%2B%285x%2B4%29%2Bc%5C%5Cc%3D%2816x-6%29-%282x-5%29-%285x%2B4%29%5C%5Cc%3D%289x-5%29%5C%20units)
