A circle has radius = 17
Calculate Area, Circumference, Radius, Diameter
Calculate circumference (C):
C = 2πr
C = 2π * 17
C = 34π or 106.8142
Calculate diameter (d):
d = 2r
d = 2 * 17
d = 34
Calculate Area (A):
A = πr2
A = π * 172
A = 289π or 907.9203
Final Answers
C = 34π or 106.8142
d = 34
A = 289π or 907.9203
d = 34
A = 289π or 907.9203
