COMPLETE THE DO NOW SILENTLY, INDEPENDENTLY, & IMMEDIATELY
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 DURING REVIEW I WILL ASK FOR VOLUNTEERS TO SOLVE THESE! EVERYONE ELSE PUT A CHECK NEXT TO A RIGHT ANSWER OR CORRECT IT!

This is what are focusing on today!
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 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 = πR2 = 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 = miles2
4
Relationship between Diameter and Radius
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?
5
We are mathematicians!!!! Work Independently 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!!!! Volume of Cubes and Rectangular Prisms 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
Circumference is distance around a circle (A circle’s Perimeter) 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 = 216ft3 DURING REVIEW PUT A CHECK NEXT TO A RIGHT ANSWER OR CORRECT IT!
8
Relationship between Diameter and Radius
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?
9
We are mathematicians!!!! Work Independently 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?
