Answer:

[tex]67.02\ in^2[/tex]

Step-by-step explanation:

-We find the surface area of the formula as follows:

[tex]A=\pi r^2, \ \ r=radius=8\ in\\\\=\pi \times 8^2\\\\=201.06\ in^2[/tex]

#We then find the area of the remaining fraction if she only ate one third:

[tex]Eaten=\frac{1}{3}\times Area\\\\=\frac{1}{3}\times 201.06\ in^2\\\\=67.02\ in^2[/tex]

Hence, Tina ate [tex]67.02\ in^2[/tex] of the pizza.
