Answer:

[tex]A=5.29\pi[/tex]

Step-by-step explanation:

Formula for circumference of a circle is:

Circumference = [tex]2\pi r[/tex]


Given circumference of the ring is [tex]4.6\pi[/tex]

Now solving for the radius gives us:

[tex]2\pi r=4.6\pi\\r=\frac{4.6\pi}{2\pi}\\r=\frac{4.6}{2}=2.3[/tex]


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

area (A) = [tex]\pi r^2\\\pi (2.3)^2\\\pi (5.29)\\=5.29\pi[/tex]


Hence the Area (A), in terms of [tex]\pi[/tex] is [tex]5.29\pi[/tex]
