Welcome Back! Week 8: Pre-Algebra - Circumference and Area of Circles has two short video (and an optional Pi Song Video) and about 13 questions.
Be sure to attempt all the questions and submit when you are finished. Please contact me through the comment feature or send an email to rshaw@fergflor if you have any questions.
Match the parts of circles:
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Diameter | arrow_right_alt |
The line from the center to the edge |
Area | arrow_right_alt |
The line across the center of the circle |
Radius | arrow_right_alt |
Around the outside of the circle |
Circumference | arrow_right_alt |
The inside of the circle |
What is the radius if the diameter is 8ft?
What is the radius if the diameter is 18 yards?
What is the diameter if the radius is 7 inches?
What is the diameter if the radius is 5 yards?
What is the area if the diameter is 18 yards?
What is the circumference of the circle? Leave your answer in terms of π. Use C = πd or C = 2πr.
What is the area of the circle? Leave your answer in terms of π. Use A = πr2
