A circle has circumference = 17
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
C = 2πr
Rearranging the equation, we get:
| r = | C |
| 2π |
| r = | 17 |
| 2 * 3.1415926535898 |
| r = | 17 |
| 6.2831853071796 |
r = 2.7056340325622
Calculate diameter (d):
d = 2r
d = 2 * 2.7056340325622
d = 5.4112680651244
Calculate Area (A):
A = πr2
A = π * 2.70563403256222
A = 7.3205π or 22.998
Final Answers
r = 2.7056340325622
d = 5.4112680651244
A = 7.3205π or 22.998
d = 5.4112680651244
A = 7.3205π or 22.998
