Circumference & Area of a Circle

Rem: First name, last initial

Find the Circumference Formula: C=∏d (circumference=pi x diameter)
pi = 3.14

1. diameter = 7.5m
2. d = 15.5ft
3. d = 10.2cm
4. d = 5mm
5. d = 22km


Find the Area Formula: A=∏r2 (Area=pi x radius squared)

6. r = 15cm
7. r = 4.25m
8. r = 7ft
9. r = 6.75yd
10. r = 10ft
