A circle has diameter = 8

Calculate Area, Circumference, Radius, Diameter

Calculate radius (r):

d = 2r

Rearranging the equation, we get:

r  =  d
  2

r  =  8
  2

r = 4

Calculate circumference (C):

C = 2πr

C = 2π * 4

C = 8π or 25.1327

Calculate Area (A):

A = πr2

A = π * 42

A = 16π or 50.2655

Final Answers

r = 4
C = 8π or 25.1327
A = 16π or 50.2655
