↓Steps Explained:↓
A circle has area = 7
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
A = πr2
Rearranging the equation, we get:
| r2 = | A |
| π |
| r = | √A |
| √π |
| r = | √7 |
| √3.1415926535898 |
| r = | 2.6457513110646 |
| 1.7724538509055 |
r = 1.4927053303605
Calculate circumference (C):
C = 2πr
C = 2π * 1.4927053303605
C = 2.9854π or 9.3789
Calculate diameter (d):
d = 2r
d = 2 * 1.4927053303605
d = 2.9854106607209
