<h3>6.</h3>

perimeter ratio = 4/7

area ratio = (4/7)² = 16/49

<h3>7.</h3>

perimeter ratio = 14/9

Express the area of a circle, a, as a function of its circumference, <br> c.
Naddika [18.5K]
Area = PI * radius^2

Circumference = 2 * PI * radius
radius = Circumference / 2 * PI

So, Area = PI * (Circumference / 2 *PI) * (Circumference / 2 *PI)
So, Area = Circumference^2 / (4*PI)
