Best ResponseYou've already chosen the best response.0Well area of a circle is \[A=\pi*r^2\] and the radius is 1/2 of the diameter. So do\[\frac{ 18 }{ 2 }=r\] And then plug the value you find into the area of a circle formula. At this point you will have the area of the total pizza. Just divide the total area by 2 to find how much she ate.
