A circle has circumference = 12

Calculate Area, Circumference, Radius, Diameter

Calculate radius (r):

C = 2πr

Rearranging the equation, we get:

r  =  C
  2π

r  =  12
  2 * 3.1415926535898

r  =  12
  6.2831853071796

r = 1.9098593171027

Calculate diameter (d):

d = 2r

d = 2 * 1.9098593171027

d = 3.8197186342055

Calculate Area (A):

A = πr2

A = π * 1.90985931710272

A = 3.6476π or 11.4593

Final Answers

r = 1.9098593171027
d = 3.8197186342055
A = 3.6476π or 11.4593
