A circle has circumference = 18
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
C = 2πr
Rearranging the equation, we get:
| r = | C |
| 2π |
| r = | 18 |
| 2 * 3.1415926535898 |
| r = | 18 |
| 6.2831853071796 |
r = 2.8647889756541
Calculate diameter (d):
d = 2r
d = 2 * 2.8647889756541
d = 5.7295779513082
Calculate Area (A):
A = πr2
A = π * 2.86478897565412
A = 8.207π or 25.7831
Final Answers
r = 2.8647889756541
d = 5.7295779513082
A = 8.207π or 25.7831
d = 5.7295779513082
A = 8.207π or 25.7831
