↓Steps Explained:↓
A circle has area = 2
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
A = πr2
Rearranging the equation, we get:
| r2 = | A |
| π |
| r = | √A |
| √π |
| r = | √2 |
| √3.1415926535898 |
| r = | 1.4142135623731 |
| 1.7724538509055 |
r = 0.79788456080287
Calculate circumference (C):
C = 2πr
C = 2π * 0.79788456080287
C = 1.5958π or 5.0133
Calculate diameter (d):
d = 2r
d = 2 * 0.79788456080287
d = 1.5957691216057
Final Answers
r = 0.79788456080287C = 1.5958π or 5.0133
d = 1.5957691216057
