Help me plz this is hard will give points

Answer:
C = 14pi
Step-by-step explanation:
C = pi d
The radius is 7 so the diameter is
d = 2r
d = 2*7
=14
C = pi *14
C = 14pi
Answer:
Step-by-step explanation:
we know circumference of a circle = [tex]\pi[/tex]d
here radius = 7 mm
diameter = 2*7= 14mm
therfore circumference = [tex]\pi[/tex] * 14
ie C = 14[tex]\pi[/tex]
therefore 2nd option is the answer
