Determine whether the relationship between the circumfrance of a circle and its diameter is a direct variation. If so, identify
kipiarov [429]

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 \pi

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 y=kx

where K is the constant of proportionality

In this problem we know that

The circumference of a circle is equal to

C=\pi D

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 \pi

If JK = 9, KI = 12, JI = 11, NL = 30, and ML = 27.5, find the perimeter of LMN. Round your answer to the nearest tenth if necess
saveliy_v [14]

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"

\frac{JK}{NM}= \frac{JI}{ML}= \frac{KI}{NL}

\frac{9}{NM}= \frac{11}{27.5}= \frac{12}{30}

\frac{9}{NM}= \frac{12}{30}

NM = \frac{9\times 30}{12}

NM = 22.5

Perimeter of the triangle LMN = ML + NM + NL

                                                  =  27.5 + 22.5 + 30

                                                  = 80 units
