r = 2.0690142601946
d = 4.1380285203893
A = 4.2808π or 13.4485
d = 4.1380285203893
A = 4.2808π or 13.4485
↓Steps Explained:↓
A circle has circumference = 13
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
C = 2πr
Rearranging the equation, we get:
| r = | C |
| 2π |
| r = | 13 |
| 2 * 3.1415926535898 |
| r = | 13 |
| 6.2831853071796 |
r = 2.0690142601946
Calculate diameter (d):
d = 2r
d = 2 * 2.0690142601946
d = 4.1380285203893
Calculate Area (A):
A = πr2
A = π * 2.06901426019462
A = 4.2808π or 13.4485
Final Answers
r = 2.0690142601946d = 4.1380285203893
A = 4.2808π or 13.4485
