Answer:

73.5

Step-by-step explanation:

circumference = 2πr , where r = radius

given radius = 11.7 so r = 11.7

C = 2πr

==> plug in r = 11.7

C = 2π(11.7)

==> multiply 2 and 11.7

C = 23.4π

==> multipl 23.4 and π

C = 73.5 ( rounded to the nearest tenth )

R = 11.7

C = [tex]2\pi r[/tex]

Step-by-step:

Subsitute r with 11.7

[tex]C = 2\pi 11.7[/tex]

Multiply 2 * 11.7

[tex]C = 23.4\pi[/tex]

Multiply 23.4 * pi

[tex]C = 73.5[/tex] :)
