Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared
Using 3.14 as Pi the area of circle is: 2461.76
It is the name given to the straight line from the centre of a circle to its circumference when that distance is 28 cm.
28 pi cm, about 88 cm
Well, honey, the circumference of a circle is calculated using the formula C = 2πr, where r is the radius. Since you didn't give me the radius, I can't give you the exact circumference. But if the diameter is 56 cm, then the radius would be half of that, which is 28 cm. Plug that into the formula and you'll get your answer.
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
The circumference is 175.92918860102841 feet.
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?
