Define:
Circumference
Diameter
Radius
Relationship of Radius to Diameter
Circumference: Distance around it
Diameter: Straight Line that passes through the center of the circle
Radius: Straight Line from the middle of the circle to the edge.
Radius is half the Diameter
Formula to calculate area of a circle
Area =π R²
Volume of a cylinder
Base times height
A cylinder with the Radius of 4 in and the height of 6 in has the volume of what?
Describe the process
Volume = Base × Height
Base = π R²
301.44 in³
How to find volume of a rectangular prism
L × W × H
Volume of a rectangular prism dimensions 4ft × 5ft× 6ft
120 ft³
Circumference formula
Circumference = π × Diameter
Circumference & Area of a Circle with a 8m Radius.
C = 50.24 m
A = 200.96 m²
True or False
Area is always a 2-dimensional quantity?
Give an example of how we write an Area quantity.
True

Circle with 24 in Diameter
Area?
Circumference?
Area: 452.16 in²
Circumference: 75.36
Difference between perimeter and area
How to calculate
Perimeter is the Lines that make up the boundary.
Area is the space inside the Perimeter
Perimeter = Sides Added together
Rectangul area = Length × Width ( Units Squared )
How to find the Length or Width of a rectangle when only the Area and 1 of the measurements are given
Area ÷ length Or width
