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

Final Answers

r = 1.4927053303605
C = 2.9854π or 9.3789
d = 2.9854106607209
