Answer:[tex]14cm^{2}[/tex]
Step-by-step explanation:
diameter=7.3cm
radius=[tex]\frac{diameter}{2}[/tex]
=[tex]\frac{7.3}{2}[/tex]
=3.65cm
angle =120°
area=[tex]\frac{angle (tita)}{360}[/tex] × [tex]\frac{\pi r^{2} }{1}[/tex]
=[tex]\frac{120}{360}[/tex] × [tex]\frac{22}{7}[/tex] ×[tex]3.65^{2}[/tex]
=[tex]13.95cm^{2}[/tex]
≅[tex]14cm^{2}[/tex]
