↓Steps Explained:↓
A circle has area = 15
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
A = πr2
Rearranging the equation, we get:
| r2 = | A |
| π |
| r = | √A |
| √π |
| r = | √15 |
| √3.1415926535898 |
| r = | 3.8729833462074 |
| 1.7724538509055 |
r = 2.1850968611842
Calculate circumference (C):
C = 2πr
C = 2π * 2.1850968611842
C = 4.3702π or 13.7294
Calculate diameter (d):
d = 2r
d = 2 * 2.1850968611842
d = 4.3701937223683
Final Answers
r = 2.1850968611842C = 4.3702π or 13.7294
d = 4.3701937223683
