A manufacturing company is producing dinner plates with a diameter of 12 inches. They plan to put a gold edge on each plate. Determine how much gold edging they need for each plate by finding the circumference of each plate. Round to the nearest tenth.
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
Answer:
37.70
Step-by-step explanation:
12xpi or 3.14= 37.68
rounded to the nearest tenth= 37.70
