A circle has area = 5
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
A = πr2
Rearranging the equation, we get:
| r2 = | A |
| π |
| r = | √A |
| √π |
| r = | √5 |
| √3.1415926535898 |
| r = | 2.2360679774998 |
| 1.7724538509055 |
r = 1.2615662610101
Calculate circumference (C):
C = 2πr
C = 2π * 1.2615662610101
C = 2.5231π or 7.9267
Calculate diameter (d):
d = 2r
d = 2 * 1.2615662610101
d = 2.5231325220202
Final Answers
r = 1.2615662610101
C = 2.5231π or 7.9267
d = 2.5231325220202
C = 2.5231π or 7.9267
d = 2.5231325220202
