A circle has area = 18
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
A = πr2
Rearranging the equation, we get:
r2 = | A |
π |
r = | √A |
√π |
r = | √18 |
√3.1415926535898 |
r = | 4.2426406871193 |
1.7724538509055 |
r = 2.3936536824086
Calculate circumference (C):
C = 2πr
C = 2π * 2.3936536824086
C = 4.7873π or 15.0398
Calculate diameter (d):
d = 2r
d = 2 * 2.3936536824086
d = 4.7873073648172
Final Answers
r = 2.3936536824086
C = 4.7873π or 15.0398
