Answer:

33.2in²

Step-by-step explanation:

to find area we have to find redious first so

  • r=d/2

therefore

[tex]r = \frac{3 \frac{1}{4} }{2} [/tex]

[tex]r = \frac{ \frac{13}{2} }{2} [/tex]

[tex]r = \frac{13}{2} \div 2[/tex]

[tex]r = \frac{13}{4} [/tex]

[tex]area \: of \: a \: circle \: = \pi {r}^{2} [/tex]

[tex] = \pi (\frac{13}{4} ) ^{2} i {n}^{2} [/tex]

[tex] = \pi \times \frac{169}{16} {in}^{2} [/tex]

[tex] = \frac{169\pi}{16} i {n}^{2} [/tex]

[tex] = 33.2 \: i {n}^{2} [/tex]
