A circle has radius = 2

Calculate Area, Circumference, Radius, Diameter

Calculate circumference (C):

C = 2πr

C = 2π * 2

C = or 12.5664

Calculate diameter (d):

d = 2r

d = 2 * 2

d = 4

Calculate Area (A):

A = πr2

A = π * 22

A = or 12.5664

Final Answers


C = or 12.5664
d = 4
A = or 12.5664
