Area of quater of circle is [tex]\frac{\pi r^2}{4}[/tex]
Radius = 3
(A = Area)
A = [tex]\frac{3^2\pi }{4}[/tex]
A = [tex]\frac{9\pi }{4}[/tex] (The order of steps doesn't matter whether you divide 9 by 4 first or times 9 with [tex]\pi[/tex]. I'm going to divide 9 with 4 first)
A = 2.25[tex]\pi[/tex]
Area (With [tex]\pi[/tex] --> 3.14 aprx.) = 7.065
