Unit 5, Lesson 16
Applying Area of Circles
Accelerated 6
Preparation
Lesson Narrative
In this lesson, students apply the formula to solve problems involving the area of shapes made up of parts of circles and other shapes such as rectangles (MP7). Students are also introduced to the idea of expressing exact answers in terms of (MP6).
The last activity is optional because it revisits a context that was explored in a previous optional activity, and it provides an additional opportunity for students to apply to solve a problem.
- Calculate the area of a shape that includes circular or semi-circular parts, and explain (orally and in writing) the solution method.
- Comprehend and generate expressions in terms of $\pi$ to express exact measurements related to a circle.
Let’s find the areas of shapes made up of circles.
Required Preparation
It is recommended that four-function calculators be made available to take the focus off of computation.
