Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared
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 = 2 x PI x radius = 28 x PI = (approx) 87.9645943"
It depends on what is meant by 28 yards: diameter? circumference?
It is the name given to the straight line from the centre of a circle to its circumference when that distance is 28 cm.
Multiply the diameter by pi, which is about 3.14.
28 pi cm, about 88 cm
The area of a 28-foot diameter circle is: 615.752 feet2If the circumference is 28 feet then the area is 62.388 feet2
