Answer:

A=346,6 in²

Alternative C

Step-by-step explanation:

Length of circunference:

L=2πR,  where r is the radius

Area of circle:

A=πR²

We know that L=66

66=2πR, then:

πR=33in

[tex]R=\frac{33}{\pi }[/tex]

Thus:

[tex]A=\pi (\frac{33}{\pi} )^{2}[/tex]

[tex]A=\frac{1089}{\pi} \\\\A=346,63[/tex]
