A circle has diameter = 14

Calculate Area, Circumference, Radius, Diameter

Calculate radius (r):

d = 2r

Rearranging the equation, we get:

r  =  d
  2

r  =  14
  2

r = 7

Calculate circumference (C):

C = 2πr

C = 2π * 7

C = 14π or 43.9823

Calculate Area (A):

A = πr2

A = π * 72

A = 49π or 153.938

Final Answers


r = 7
C = 14π or 43.9823
A = 49π or 153.938
