Answer:

16.55cm

Explanation:

c=πd

104=22÷7d

multiply all sides by 7

728=22d

divide all sides by 22 to get d=33.09

r=d ÷2

r=33.09÷2

=16.55cm

Answer:

radius=20

Explanation:

c= circumference

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

104=2[tex]\pi[/tex]r

[tex]\frac{104}{2\pi }[/tex]=r

[tex]\frac{104}{6.28}[/tex]=r

16.56=r

20=r (to the nearest 10)
