What is the circumference of a circle with a diameter of 3?
| 38π | |
| 12π | |
| 3π | |
| 26π |
The formula for circumference is circle diameter x π:
c = πd
c = 3π
What is the area of a circle with a diameter of 8?
| 36π | |
| 25π | |
| 81π | |
| 16π |
The formula for area is πr2. Radius is circle \( \frac{diameter}{2} \):
r = \( \frac{d}{2} \)
r = \( \frac{8}{2} \)
r = 4
a = πr2
a = π(42)
a = 16π
