Given:

Diameter = 12 inches.

Find: Circumference of the dinner plates.

Circumference = 2 π r

π = 3.14

r = diameter / 2 = 12/2 = 6 inches

Circumference = 2 * 3.14 * 6 inches

Circumference = 37.68 inches

37.68 inches rounded to the nearest tenth is 37.70 inches.

Circumference can also be computed by multiplying pi and the diameter.

C = 3.14 * 12 inches

C = 37.68 inches
