Given:
Diameter = 6 inches
Determine the Circumference.
Formula for the circumference of the circle:
C=2πr
Solution:
We must first find the value of r, in which case we know that,
d = 2r
r = d/2
r = 6 inches/2
r = 3 inches
Substitute the value of 3 to the formula for the circumference.
C=2π(3 inches)
C=6π inches
C= 18.8 inches
C = 19 inches
Final answer:
C = 19 inches
