Area = pi*9*9 square inches

The formula for area of a circle is: A = (pi)*r^2 If the diameter of a circle is 6 then the circle's radius is 3. So, A = (pi)*(3)^2 A= 9*(pi) inches squared or A = 28.26 inches squared (rounded)

The circumference of 9 inch diameter circle is about 28.27 inches.

Radius = Diameter/2. So in this case 4.5 inches.

-- The circumference of any circle is (pi) x (diameter) = 9 pi = 28.274 inches.-- The radius of a circle is 1/2 of its diameter. The radius of the dinner plate is 4.5 inches.-- The area of a circle is (pi) x (radius)2. The area of the dinner plate is probablya bit more than that, because it's not a flat surface.-- The area of the flat circle in the plane defined by the rim of the plate is(pi) x (4.5)2 = 20.25 pi = 63.617 square inches(rounded)
