Idon't fully understand how to find this can someone explain?

≈35.355 cm.

Step-by-step explanation:

If both pizza specials are the same size, the total area of each special must be the same.

We can already solve for the area of the Fibonacci Special, since we are given the diameter of the pizzas. The area of a circle is solve with the equation A = π r^2. The radius, r, is equal to half the diameter, so 25/2 = 12.5cm. Now, 2(π * 12.5^2) = 981.748 cm^2. The number was multiplied by 2 since there are two pizzas in the Fibonacci Special.

Now that we know what the area for the pizza in the Galileo Special is, we can adjust the area equation to solve for the diameter of the pizza. A = π r^2, changed to Diameter = 2(SQRT(A/π)), which substitutes 2r for Diameter.

Now solving it:

2(SQRT(981.748/π)) ≈  35.355 cm.
