-- 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 probably
a 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)
Twelve inches is a length. It can be a diameter, but if it is a diameter, you would simply say 'The circle is 12 inches diameter'. So; how big is it - it is 12 inches.
The diameter of the circle will be: 26.1 inches.
If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).
Frisbees come in different sizes. The diameter can be 8 inches, 10 inches, 12 inches, or another diameter.
If a circle has a diameter of 12.8 inches its circumference is: 40.21 inches (circumference = diameter x Pi).
14 pi inches = a whisker under 44 inches
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 = ∏ 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.
circumference about 28.27 inches area about 63.62 square inches
1 revolution = 1 circumference = (4 pi) inches1,000 revolutions = 1,000 circumferences = (4,000 pi) inches =12,566.4 inches (rounded)1 furlong 129 yards 2.37 inches (rounded)
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
The inches in a diameter = 2 X inches in the radius. Or, inches in a diameter = inches in circumference / pi

What is a "8 inch ball" ? Is 8 inches the diameter ? Then its diameter is 8 inches. Is 8 inches the radius ? Then its diameter is 16 inches. Is 8 inches the circumference ? Then its diameter is about 2.546 inches (rounded).
the diameter would be 7 inches
Diameter = 117/pi inches
