Question

Two restaurants offer customers large pizzas using different measurements for diameter.

Restaurant 1: One large 16-inch pizza for $14.99
Restaurant 2: One large 41.91-centimeter pizza for $14.99
If 1 inch = 2.54 centimeters, what is the length of the crust around the larger pizza, using π = 3.14?

Answer 1

We can start by finding the diameter of the larger pizza in inches:

41.91 cm ÷ 2.54 cm/inch = 16.5 inches (rounded to one decimal place)

The diameter of the larger pizza is about 16.5 inches. Using this value, we can find the circumference (length of the crust) of the larger pizza using the formula:

C = πd

where C is the circumference and d is the diameter.

C = 3.14 × 16.5 inches

C ≈ 51.81 inches (rounded to two decimal places)

Therefore, the length of the crust around the larger pizza is about 51.81 inches.
