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
