Answer:
4 = the top row would be 1,2,3,4,5
the bottom row would be 14,28,42,56,70
the equation is y= 14x
5 = yes it is proportional. y=21x
6 =no it is not proportional.
7 = yes it is proportional because y= 7x
Step-by-step explanation:
To find the circumference of a circle you use the formula, C=2*pi*radius or C=pi*diameter, in his case you would use the first option, C=2*pi*radius, because the radius is the given value. You then plug the values into the equation to solve for the circumference...
C=2*pi*15
C=30*pi
C=30pi or approximately 94.2478
