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

16m²

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
