What is the radius of this pizza?
Understand the Problem
The question is asking for the radius of a pizza, which involves understanding the concept of radius in geometry. We need to determine the correct answer from the multiple-choice options given.
Answer
The radius of the pizza is $12$ inches.
Answer for screen readers
The radius of the pizza is $12$ inches.
Steps to Solve
- Identify the radius definition The radius of a pizza is half of its diameter. If the diameter is known, the radius can easily be calculated using the formula:
$$ r = \frac{d}{2} $$
-
Use visual approximation (if applicable) If the diameter is not given, visual estimation might be needed. For example, common pizza diameters include 12 inches, 14 inches, and sometimes larger, depending on the size of the pizza.
-
Review multiple-choice options Compare the common pizza sizes with the options provided: 144 inches, 24 inches, and 12 inches.
-
Select the most reasonable answer Considering typical pizza sizes, 12 inches seems to be the most realistic option based on known pizza dimensions.
The radius of the pizza is $12$ inches.
More Information
The size of pizzas commonly ranges from 10 to 18 inches in diameter, meaning typical radii are from 5 to 9 inches. A 12-inch radius would indicate either an extraordinarily large pizza or a misconception; however, given the typical options, 12 inches is a logical selection.
Tips
- Assuming that 144 inches might be a reasonable size for a pizza, when in reality, that is extraordinarily large and impractical.
- Not knowing that the radius is half of the diameter, leading to incorrect calculations or estimations.
