A dinner plate has a circumference of 125.6 cm. What is the area of the dinner plate? (Use 3.14 for .)
Circumference = ∏ x diameterSo circumference of a dinner plate with diameter 10inches = 10∏ = 31.14inches (2.d.p)
Circumference = 28.2743339 inches. Area = 63.6172512 square inches.
Diameter = 12 inches, Circumference = 12*(pi) = approx. 37.699 Radius = 12 inches, Circumference = 2*12*(pi) = 24*(pi) = approx. 75.398 inches If the author has actually measured the outside of the circle (i.e. the perimeter of a dinner plate), that is the circumference! Problem solved.
The area of the plate is equal to pi times the square of the radius. Since the plate has a 10 inch diameter, the radius is 5 inches. Therefore, the area is equal to pi times 25, or about 78. 5 inches.
The area is about 78.5 square inches. The formula for the area of a circle is A = pi r2 where r is the radius (half of the diameter) 3.1416 x (5)2 = 3.1416 x 25 = about 78.54 square inches

To calculate the circumference of a paper plate, you can use the formula ( C = \pi d ), where ( d ) is the diameter of the plate. For example, if the diameter of the plate is 10 inches, the circumference would be approximately 31.4 inches (using ( \pi \approx 3.14 )). The actual circumference will vary depending on the specific size of the plate you have.
-- 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)
Diameter = 12 inches, Circumference = 12*(pi) = approx. 37.699 Radius = 12 inches, Circumference = 2*12*(pi) = 24*(pi) = approx. 75.398 inches If the author has actually measured the outside of the circle (i.e. the perimeter of a dinner plate), that is the circumference! Problem solved.
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. The radius of the dinner plate is 5.5 inches (half of the diameter), and the radius of the salad plate is 4 inches. The area of the dinner plate is 95.03 square inches (π * 5.5^2), while the area of the salad plate is 50.27 square inches (π * 4^2). The dinner plate covers 44.76 square inches more than the salad plate.
A third of a typical dinner plate would cover about a third of the plate's surface area, usually around 6-7 inches in diameter.
The circumference of a standard dinner plate is typically around 70 centimeters.
Assuming the plate to be circular, its circumference could be written as: Circumference = 2πr, where, π = 22/7 and r is the radius of the plate. If you need have the diameter of the plate, you can find its circumference using: Circumference = πd, where d represents the diameter of the plate.
The area of the plate is equal to pi times the square of the radius. Since the plate has a 10 inch diameter, the radius is 5 inches. Therefore, the area is equal to pi times 25, or about 78. 5 inches.
The area is about 78.5 square inches. The formula for the area of a circle is A = pi r2 where r is the radius (half of the diameter) 3.1416 x (5)2 = 3.1416 x 25 = about 78.54 square inches
