Circle radius = 7 
A circle has radius = 7
Calculate Area, Circumference, Radius, Diameter
Calculate circumference (C):
C = 2πr
C = 2π * 7
C = 14π or 43.9823
Calculate diameter (d):
d = 2r
d = 2 * 7
d = 14
Calculate Area (A):
A = πr2
A = π * 72
A = 49π or 153.938
Final Answers
C = 14π or 43.9823
d = 14
A = 49π or 153.938
What is the Answer?
C = 14π or 43.9823
d = 14
A = 49π or 153.938
