Given:
Diameter = 6 inches
Determine the circumference of the circle.
Formula for the circumference of the circle:
C=2πr
Solution:
Solve first for the radius in terms of d.
d = 2r
r = d/2
r = 6/2
r = 3 inches
Substitute the value of 3 to the formula for the circumference of the circle.
C=2πr
C=2π(3 inches)
C=6π inches
C = 18.85 inches
