Answer:

Medium pizza is 62.83 square inches greater than smaller pizza.

Step-by-step explanation:

Given:

Diameter of smaller pizza = 8 inch

Diameter of medium pizza = 12 inch

We need to find how much greater in area is medium pizza than the small pizza.

Solution:

First we will find the are of both the pizza;

Now we know that;

Radius = [tex]\frac12[/tex] Diameter

Radius of Smaller pizza = [tex]\frac12\times8 =4 \ in.[/tex]

Radius of Medium pizza= [tex]\frac12\times12 =6 \ in.[/tex]

Now pizza is in circular shape so we will apply area of circle to find the area of the pizza.

Area of circle is π times square of the radius.

framing in equation form we get;

Area of Smaller Pizza = [tex]\pi \times 4^2= 16 \pi= 50.265\ in^2[/tex]

Area of Medium Pizza = [tex]\pi \times 6^2= 36\pi = 113.097\ in^2[/tex]

Now to find Difference we will subtract Area of Smaller Pizza from Area of Medium Pizza.

So we can say that;

Difference = [tex]113.097-50.265 = 62.832\ in^2[/tex]

Rounding to nearest hundred we get;

Difference = [tex]62.83\ in^2[/tex]

Hence Medium pizza is 62.83 square inches greater than smaller pizza.
