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.
a nine inch circular dinner plate is about 64 square inches
Circumference of plate: 4.3*pi = 13.5 rounded to one decimal place
Perimeter of a round plate = 2*pi*radius or pi*diameter
25pi
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.
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 circular plate is calculated using the formula A = πr^2, where r is the radius of the circle. Given that the radius of the circular plate is 12 centimeters, the area would be A = π(12)^2 = 144π square centimeters, which is approximately 452.39 square centimeters.
Circumference = 28.2743339 inches. Area = 63.6172512 square inches.
The pie plate with the 5-inch diameter is greater.
Use the equation for circumference: C = pi * d Plug in 10 inches for "d" => C = 3.14 * 10 inches = 31.4 inches 31.4 inches is the circumference of a dinner plate with a diameter of 10 inches. Key: C = circumference d = diameter pi = 3.14
circumference about 28.27 inches area about 63.62 square inches
Circumference = ∏ x diameterSo circumference of a dinner plate with diameter 10inches = 10∏ = 31.14inches (2.d.p)
-- 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)
a nine inch circular dinner plate is about 64 square inches
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.
Well, sugar, if the radius of a baseball is 1.5 inches and home plate is 16 inches wide, we can calculate the circumference of the baseball (3.14 x diameter) and then divide the width of home plate by that distance to find out how many rotations it would take. So, it would take approximately 3 rotations for that sassy baseball to roll across home plate.
