It is estimated that Americans eat 100 acres worth of pizza a day. Assume that they are large pizzas with a diameter of 14 inches.
Find the number of square inches in a large pizza.
An acre has 43,560 square feet and a square foot has 144 square inches. How many square inches are there in 100 acres?
How many large pizzas do Americans eat each day?
If a large pizza has eight slices, estimate how many slices per second American eat.
What is another real world situation in which similar calculations are used?
Explanation / Answer
the number of square inches in a large pizza. = Area of the circle with diametre 14 inches
= pir^2
= 154 square inches.
----------------------------------------------------------
An acre = 43560 square feet
Hence in 100 acres = 4356000 sq ft =
4356000x144 square inches
= 627,264,000 square inches.
-----------------------------------------------------------
no of pizzas eaten by Americans each day = 627,264,000/154 = 4073143
--------------------------------------------------------
Slices they eat = 4073143x8 = 32585143 slices
