1. Do Now C = π x D; D = 2R; R = ½ D. Find the 1). Radius if the Diameter is 8 miles 2). Diameter if the Radius is 12 inches 3). The circumference if the radius is 3 feet 4). The diameter if the circumference is 6.28 feet COMPLETE THE DO NOW SILENTLY, INDEPENDENTLY, & IMMEDIATELY DURING REVIEW I WILL ASK FOR VOLUNTEERS TO SOLVE THESE! EVERYONE ELSE PUT A CHECK NEXT TO A RIGHT ANSWER OR CORRECT IT!

2. Objective & EU OBJECTIVE: SWBAT calculate the volume of a cube/rectangular prism and the area of a circle. ESSENTIAL UNDERSTANDING: Area is the second dimension; cubes are the third dimension This is what are focusing on today! Come out of this lesson with your essential understanding!

3. Area of a Circle The area is the space inside a circle. The formula is: A = πR 2 = π x R x R. Units are always squared! Example: What is the area of a circle with a radius of 2 miles? Answer: π x 2m x 2m = 12.56 miles 2 WHEN FINISHED SIT IN ACADEMIC POSTURE!

4. Let’s Try Together 1). What is the area of a circle with a radius of 3 miles? 2). What is the area of a circle with a radius of 5 inches? 3). What is the area of a circle with a diameter of 8 miles? Relationship between Diameter and Radius

5. Work Independently We are mathematicians!!!! 1). What is the area of a circle with a radius of 10 meters? 2). What is the area of a circle with a diameter of 2 feet? 3). What is the area of a circle with a radius of 24 inches? 4). What is the area of a circle with a diameter of 9 meters?

6. Volume of Cubes and Rectangular Prisms We are mathematicians!!!! A cube is a three dimensional square A rectangular prism is a three dimensional rectangle.

7. It is easy to calculate volume of cubes rectangular prisms Volume = Base x Width x Height What is the volume of a cube With a side of 6 feet? 6ft x 6ft x 6ft = 216ft 3 Circumference is distance around a circle (A circle’s Perimeter) DURING REVIEW PUT A CHECK NEXT TO A RIGHT ANSWER OR CORRECT IT!

8. Let’s Try Together 1). What volume of a rectangular prism that measures 2 meters x 5 meters x 8 meters? 2). What is the volume of a cube that is 10ft per side? 3). What is the volume of a rectangular prism that is 5inches x 10 inches x 2 inches? Relationship between Diameter and Radius

9. Work Independently We are mathematicians!!!! 1). What is the volume of a cube that is 8 ft per side? 2). What is the volume of a rectangular prism that is 1ft x 12ft x 10ft? 3). What is the volume of a cube that is 7ft per side? 4). What is the volume of a rectangular prism that is 11ft x 40 ft x 18ft?

10. A present for Miss Awesome We are mathematicians!!!!
