Answer:

#color(violet)("Diff. in circumferences " C_d = C_p - C_s = 8pi ~~ 25.13 cm#

Explanation:

#color(crimson)("Circumference of a circle " C = 2 * pi * r#

#"Given : radius of saucer " r_s = 8 cm, "radius of plate " r_p = 12 cm#

#:. "Circumference of saucer " C_s = 2 pi * 8 = 16 pi " cm"#

#:. "Circumference of plate " C_p = 2 pi * 12 = 24 pi " cm"#

#color(violet)("Diff. in circumferences " C_d = C_p - C_s = 24pi - 16pi = 8pi ~~ 25.13 cm#
