↓Steps Explained:↓
A circle has area = 4
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
A = πr2
Rearranging the equation, we get:
| r2 = | A |
| π |
| r = | √A |
| √π |
| r = | √4 |
| √3.1415926535898 |
| r = | 2 |
| 1.7724538509055 |
r = 1.1283791670955
Calculate circumference (C):
C = 2πr
C = 2π * 1.1283791670955
C = 2.2568π or 7.0898
Calculate diameter (d):
d = 2r
d = 2 * 1.1283791670955
d = 2.256758334191
