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
