It is the name given to the straight line from the centre of a circle to its circumference when that distance is 28 cm.

Using 3.14 as Pi the area of circle is: 2461.76

28 pi cm, about 88 cm

If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).

The circumference of a circle with a diameter of 28 cm will be pi*28 cm which is approx 88.0 cm

The circumference is 175.92918860102841 feet.

The circumference of a circle with the radius of 28 inches is 175.9 inches. (C = r x 2 x Pi).

pi = 3.1416 ( a constant) Circumference = 2 * pi * radius, so radius = circumference / (2 * pi) So radius = 28 / ( 2 * 3.1416 ) = 4.456 units

Formula of Circumference = 2πr 2πr = 28π 2r = 28 r = 14 The radius is 14

You divide the diameter by two to get the radius (28 / 2 = 14)

Circumference=2diameter(pi) C=2(28)(pi) C=175.92918860102842135390802946365

Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared

Circumference = 2 x PI x radius = 28 x PI = (approx) 87.9645943"

It depends on what is meant by 28 yards: diameter? circumference?
