A circle has circumference = 11

Calculate Area, Circumference, Radius, Diameter

Calculate radius (r):

C = 2πr

Rearranging the equation, we get:

r  =  C
  

r  =  11
  2 * 3.1415926535898

r  =  11
  6.2831853071796

r = 1.7507043740108

Calculate diameter (d):

d = 2r

d = 2 * 1.7507043740108

d = 3.5014087480217

Calculate Area (A):

A = πr2

A = π * 1.75070437401082

A = 3.065π or 9.629

Final Answers


r = 1.7507043740108
d = 3.5014087480217
A = 3.065π or 9.629
