A circle has circumference = 3
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
C = 2πr
Rearranging the equation, we get:
| r = | C |
| 2π |
| r = | 3 |
| 2 * 3.1415926535898 |
| r = | 3 |
| 6.2831853071796 |
r = 0.47746482927569
Calculate diameter (d):
d = 2r
d = 2 * 0.47746482927569
d = 0.95492965855137
Calculate Area (A):
A = πr2
A = π * 0.477464829275692
A = 0.228π or 0.7163
Final Answers
r = 0.47746482927569d = 0.95492965855137
A = 0.228π or 0.7163
