Question

23) The Dinner Plate

7.G.B.4
A dinner plate has a
diameter of approximately
13 inches. What is the
circumference of the
dinner plate? What is the
area of the dinner plate?
Use 3.14 for pi. Draw a
picture of a dinner plate
and label the dimensions
(radius and diameter).
Write the circumference
and area on your drawing.

Answer 1

Diameter is 13 inches

C = pi ( diameter)
C = 3.14 x 13
C= 40.84

To find the radius
R = d/2
R = 13/2
R = 6.5

Find the area
A=pi (r^2)
A= 3.14 (6.5^2)
A= 132.73

Answer 2

circumference is 40.84 and the area is 132.73
