Ok, so
Remember that the formula of the area of a sector of a circle is given by:
[tex]A=\frac{1}{2}r^2\theta[/tex]
Where r is the radius of the circle and Θ is the angle (in radians) of the sector.
Therefore, we would need to know the radius of the pizza, and the angle of each slice of pizza in order to calculate which one had a larger area.
