A circle has circumference = 9
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
C = 2πr
Rearranging the equation, we get:
| r = | C |
| 2π |
| r = | 9 |
| 2 * 3.1415926535898 |
| r = | 9 |
| 6.2831853071796 |
r = 1.4323944878271
Calculate diameter (d):
d = 2r
d = 2 * 1.4323944878271
d = 2.8647889756541
Calculate Area (A):
A = πr2
A = π * 1.43239448782712
A = 2.0518π or 6.4459
Final Answers
r = 1.4323944878271
d = 2.8647889756541
A = 2.0518π or 6.4459
d = 2.8647889756541
A = 2.0518π or 6.4459
