Joe ordered an 18 inch pizza with pineapple and ham on it from Mr. T's Famous Chicago Style Pizzeria. The pizza was cut into 6 slices. Joe ate only two slices and decided he didn't like the famous pizza and discarded the rest. How many square inches of pizza did he throw away? Use 3.14 for pi. Round to the nearest tenth of a square inch.

Step-by-step explanation:

Given

Required

Determine the area of the discarded part

First, calculate the area of the pizza.

Substitute 18 for D and 3.14 for

If he eats 2 out of the 6 slices, then it means he discarded 4 out of the 6.

So, the area of the 4 is:

-- approximated

The area of the discarded is 170 square inches

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
