Aclass measured the radius and circumference of various circular objects. the results are plotted on the graph. 7,44 6,38 4,25 3,18. a. does there appear to be a proportional relationship between the radius and circumference of a circle? explain or show your reasoning. b. why might the measured radii and circumferences not be exactly proportional?

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

it should be a.

hope it

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

5.7622

step-by-step explanation:

the ten thousandths place is the 2. you round it up if, that number in whatever place is 5 or higher.
