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.
-- 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)
Radius = Diameter/2. So in this case 4.5 inches.
63.585 inches
Area = 63.6 square inches.
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches
Exact area of the circle: 9*pi inches
Area = pi*9*9 square inches
Exact area of the circle: 9*pi 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)
Using 3.14 as Pi the area of circle is: 28.259999999999998
The circumference of 9 inch diameter circle is about 28.27 inches.
