Rewrite as (2^1/2 + 2^1/2)*(18^1/2-2^1/2) = 8
Answer:
The relationship between the circumference of a circle and its diameter represent a direct variation and the constant of proportionality is equal to the constant 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
where K is the constant of proportionality
In this problem we know that
The circumference of a circle is equal to

therefore
the relationship between the circumference of a circle and its diameter is a direct variation and the constant of proportionality is equal to the constant

Answer:
Perimeter of ΔLMN = 80 units
Step-by-step explanation:
From the figure attached,
m∠K = m∠N = 58°
m∠J = m∠M = 76°
m∠I = m∠L = 46°
Therefore, ΔKJI and ΔNML are the similar triangles.
By the property of similar triangles,
"Corresponding sides of two similar triangles are proportional"



NM = 
NM = 22.5
Perimeter of the triangle LMN = ML + NM + NL
= 27.5 + 22.5 + 30
= 80 units
