Answer:

  • No

Step-by-step explanation:

The proportional relationship is:

  • y = kx, where k is constant

This can be shown as:

  • y/x = k

Now let's assume x = circumference and y = area

Use respective equations:

  • A = πr², C = 2πr

If the relationship is proportional we should have:

  • A = kC ⇒ A/C = k

Verify:

  • A/C = πr²/(2πr) = r/2, this is not constant, therefore the answer is negative
