A circle has diameter = 12

Calculate Area, Circumference, Radius, Diameter

Calculate radius (r):

d = 2r

Rearranging the equation, we get:

r  =  d
  2

r  =  12
  2

r = 6

Calculate circumference (C):

C = 2πr

C = 2π * 6

C = 12π or 37.6991

Calculate Area (A):

A = πr2

A = π * 62

A = 36π or 113.0973

Final Answers


r = 6
C = 12π or 37.6991
A = 36π or 113.0973
