If the radius of the circle is 3 inches, then the area would be found by using the formula [tex]\pi r^2[/tex]. You plug it in, and the formula would get us that the area is [tex]9 \pi[/tex] square inches. Since [tex]\frac{360}{90}[/tex] would equal 4, you would do [tex]\frac{9}{4}[/tex], which would equal [tex]2 \frac{2}{5}[/tex]
SORRY IF MY TEX FAILS
