$A=5.29\pi$

Step-by-step explanation:

Formula for circumference of a circle is:

Circumference = $2\pi r$

Given circumference of the ring is $4.6\pi$

Now solving for the radius gives us:

$2\pi r=4.6\pi\\r=\frac{4.6\pi}{2\pi}\\r=\frac{4.6}{2}=2.3$

We know that area of a circle is $\pi r^2$ , substituting the value of r we found, we get the area as:

area (A) = $\pi r^2\\\pi (2.3)^2\\\pi (5.29)\\=5.29\pi$

Hence the Area (A), in terms of $\pi$ is $5.29\pi$
