The circumference of a circle with a diameter of 28 cm will be pi*28 cm which is approx 88.0 cm
If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).
Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared
Perimeter (or circumference) of a circle = pi x diameter = pi x 28, but we need the circumference of only half of it (semicircle is half of a circle) Hence the answer is pi x 14 = 3.1415 x 14 = 43.981 mm
28"
Not sure of your question since you already have the values for both equations, so I assume you want to calculate what the diameter is. If this is so, you can use the formula for finding circumference to calculate the diameter: c = pi*d (next substitute with the given values) 87.92 = 3.014*d (next divide both sides by 3.14 to find the diameter) 28 = d 28 this is the diameter of a circle that has a circumference of 87.92
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 28 unit diameter is: 88cir=dx22/7
Circumference of circle: 28 times pi inches
Circumference of the circle: 28*pi inches
Circumference = pi*diameter = 87.96 inches.
It is: pi*28 meters
Multiply the diameter by pi, which is about 3.14.
d = 8.9 feet
You divide the diameter by two to get the radius (28 / 2 = 14)
28 x 3.1416: circumference is pi times the diameter.
Circumference=2diameter(pi) C=2(28)(pi) C=175.92918860102842135390802946365
It depends on what is meant by 28 yards: diameter? circumference?
