The term "diameter" typically refers to a measurement of a circle, indicating the distance across the circle through its center. If you're asking about the diameter of a circle with an area of 28 square units, you would first calculate the radius using the formula for the area of a circle, (A = \pi r^2), and then double the radius to find the diameter. However, if you're referring to something else, please clarify!
A circle with a diameter of 28 is a circle.
28/2 = 14
28 diameter = 2 X the radius 2 X 14 = 28
You divide the diameter by two to get the radius (28 / 2 = 14)
28 x 3.1416: circumference is pi times the diameter.
A circle with a diameter of 28 is a circle.
Diameter is 28 inches
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
28/2 = 14
28 diameter = 2 X the radius 2 X 14 = 28
The circumference of a circle with a diameter of 28 cm will be pi*28 cm which is approx 88.0 cm
Diameter equal 2r (d=2r) So if your Diameter is 28 then: 28=2r (divide 2 on both sides) 14=r therefor the radius is 14
You divide the diameter by two to get the radius (28 / 2 = 14)
28 x 3.1416: circumference is pi times the diameter.
The diameter would be 28 cm.
Diameter = 2*radius = 28 cm
