A circle has circumference = 2
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
C = 2πr
Rearranging the equation, we get:
| r = | C |
| 2π |
| r = | 2 |
| 2 * 3.1415926535898 |
| r = | 2 |
| 6.2831853071796 |
r = 0.31830988618379
Calculate diameter (d):
d = 2r
d = 2 * 0.31830988618379
d = 0.63661977236758
Calculate Area (A):
A = πr2
A = π * 0.318309886183792
A = 0.1013π or 0.3182
Final Answers
r = 0.31830988618379d = 0.63661977236758
A = 0.1013π or 0.3182
