Answer:

Step-by-step explanation:

d = c/pi

so d = 62.8/pi

    d = 62.8/pi or appr 19.99in

r = d/2

so r = 62.8/2pi or 31.4/pi appr 19.99/2

a = \pi  r^{2}

so

a = \pi *(31.4/\pi)^2

then

a = 985.96/pi

so

a = approximately 313.84

answer is rowan

alex41 [277]

Answer:

Step-by-step explanation:

3000   600

5000   1000

6000   1200

7500   1500

No it doesn't form a proportional relationship because yes, the ratio is constant AFTER the 5,000, you do need to hit the 5,000 first, and then it changes. So no, it's not proportional because it isn't constant throughout the entirety of the relationship. If you're just going based on the table in question, then yes it will be proportional since it doesn't have the 5,000 in it but if you're looking at it in it's entirety, no it's not.
