A circle has circumference = 2

Calculate Area, Circumference, Radius, Diameter

Calculate radius (r):

C = 2πr

Rearranging the equation, we get:

r  =  C
  

r  =  2
  2 * 3.1415926535898

r  =  2
  6.2831853071796

r = 0.31830988618379

Calculate diameter (d):

d = 2r

d = 2 * 0.31830988618379

d = 0.63661977236758

Calculate Area (A):

A = πr2

A = π * 0.318309886183792

A = 0.1013π or 0.3182

Final Answers


r = 0.31830988618379
d = 0.63661977236758
A = 0.1013π or 0.3182
