Answer: a.) Circle B

b.) 9.42

Explanation:

A diameter of 9 cm means that the circumference of Circle A is approximately 28.26 cm.

Circumference = Diameter x π

9 x 3.14 = 28.26

A radius of 6 cm means the circumference of Circle B is approximately 37.68 cm.

Circumference = 2 x Radius x π

2 x 6 x 3.14 = 37.68

37.68 > 28.26

37.68 - 28.26

For these types of problems, I recommend numbermaniacs.com .

Have a nice day!
